-1/4-a-4=7/4a-3
solving equations with one unlike equations

Answers

Answer 1

Answer:

  a = -5/11

Step-by-step explanation:

You want to solve the equation -1/4-a-4=7/4a-3.

Solution

The first step in solving this 3-step equation can be to add the opposite of (-a) so that the variable 'a' appears only on one side of the equation:

  -1/4 -a -4 +a = 7/4a -3 +a

  -17/4 = 11/4a -3 . . . . . . . . . . . simplify

The second step is to add the opposite of the constant (-3) so that the constant is on one side of the equation, and the variable is on the other side.

  -17/4 +3 = 11/4a -3 +3

  -5/4 = 11/4a . . . . . . . . . . simplify

The third step is to multiply by the inverse of the coefficient of the variable:

  (4/11)(-5/4) = (4/11)(11/4a)

  -5/11 = a . . . . . . . . . . . . . . . simplify

Check

  -1/4 -(-5/11) -4 = (7/4)(-5/11) -3

  -17/4 +5/11 = -35/44 -3

  (-187 +20)/44 = (-132 -35)/44

  -167/44 = -167/44 . . . . . . answer checks OK

determine the midpoint of the line segment connecting (6,-5) and (-1,-6)

Answers

The midpoint of the line joining (6,-5) and (-1,-6) is (-5/2,-11/2).

How to determine the midpoint of the line joining two points (a,b) and (p,q)?

To get the midpoint of the line joining two points (a,b) and (p,q), we first have to add the x coordinates of two points and divide it by 2. So the midpoint's x coordinate will be (a+p)/2 . Similarly, we have to do the same with y. Then the midpoint of the line joining two points (a,b) and (p,q) will be [(a+p)/2,(b+q)/2}.

To get the midpoint of (6,-5) and (-1,-6) , first, we have to add the x coordinates and divide it by 2 . And have to do the same with y.

so, the midpoint will be [(6+(-5)]/2,[-5+(-6)]/2.

Hence ans will be ,(-5/2,-11/2)

Answer:

y=1/2x-9/2

Step-by-step explanation:

First you want to find the slope by doing -2-(-1)/5-7

Therefore the slope is 1/2

Next you want to add in any set of points, either (5, -2) or (7, -1)

Substitute the x- point in place of x and the y in place of y in y=1/2x+b

Once you do this you should get -2=1/2(5)+b

You should get -2=2 1/2+b

Then subtract 2 1/2 from -2

You should get -4 1/2

Once you have the slope and y- intercept you can put together your problem

y=1/2x-4 1/2

don't forget to convert, y=1/2x-9/2

d=cost of a bag of dog food
Write Two Equation
?
?

Answers

One bag of cat food costs $6 and one bag of dog food costs $9.

What is system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

The problem states that c equals the cost of bag of cat food and d equals the cost of bag of dog food.

Last week she paid $117 for 6 bags of cat food and 9 bags of dog food.

Therefore, the equation becomes,

6c + 9d = 117         ..(1)

This week she paid $87 for 4 bags of cat food and 7 bags of dog food.

Therefore, the equation becomes,

4c + 7d = 87         ..(2)

Now to solve the system of equations

To solve the first equation for c.

6c + 9d = 117

6c = 117 - 9d

[tex]c = \frac{117}{6}-\frac{9d}{6}[/tex]

Plug value of c in equation (2).

[tex]4(\frac{117}{6}-\frac{9d}{6}) +7d = 87\\78 - 6d + 7d = 87\\d = 87-78\\d = 9[/tex]

Plug d = 9 in equation (1)

6c + 9(d) = 117

6c + 9(9) = 117

6c + 81 = 117

6c = 117 - 81

6c = 36

c = 6

Hence, one bag of cat food costs $6 and one bag of dog food costs $9.

A standard deck of playing cards has 4 different suits (hearts, spades, clubs and diamonds) and 13 different ranks for the cards (ace, 2-10, jack, queen, king). In a poker game you are dealt a hand of 5 cards.
How many ways are there to get dealt exactly a single pair? A pair is a hand with two cards of the same rank. (so two pairs, three of a kind, four of a kind, full house etc. aren't included)

Answers

The number of ways that there are to get dealt exactly a single pair is; 6,589,440 ways

What is the probability of Selection?

The combination in probability selection is defined as a method where we count the number of ways a certain number of objects can be arranged in "n" different ways. If the number of different objects are "n", then it means that the number of ways that we can select "r" number of different objects is expressed as:

nCr = n!/(r!(n - r)!)

The total number of cards that we have in a deck of cards = 52.

There total number of different cards are 13 in number and this tells us that we can possibly have a pair of any one of the 13 cards. There are also 4 cards of the same rank and this means that the number of ways of selecting two cards of the same rank is; 4C2 = 6 ways

After selecting a card for the pair, we have 48 different cards as an option for the third card. Thereafter, we will have a total of 44 cards as an option for the fourth card and then 40 cards will be an option for the fifth card (due to the fact that none of the cards can be of same rank except for the pair of cards).

Therefore, the total number of ways that we can deal with exactly a single pair can be expressed as:

Number of ways = number of ways for the pair × number of ways for the third card × number of ways for the fourth card × number of ways for the fifth card

Plugging in the relevant values gives;

Number of ways = (13 × 6) × 48 × 44 × 40

= 6,589,440 ways

75 less than the product of 30 and a number is -225. What is the number?

Answers

Answer:

The Number is -5

Step-by-step explanation:

We will form the Equation and solve for the Number

Let the Number be x

Product of 30 and a Number = 30x

75 less than the Product of 30 and a Number = 30x - 75

75 less than the Product of 30 and a Number is -225

Then 30x - 75 = -225

Now solve for x (the Number)

add 75 for both sides

30x = -225 + 75 = -150

Divide both sides by 30

x = -150 / 30 = -5

Raina, Trey, and Deandre have a total of $145 in their wallets. Raina has $10 more than Trey. Deandre has 3 times what Raina has. How much do they have in their wallets?

Answers

Trey, Raina, and Deandre have $21,$31, and $93 in their wallets respectively.

From the question the sum of the money in their wallets is:

Raina  +  Trey +Deandre=$145

      R   +    T    +       D      =$145................(i)

Raina has $10 more than Trey= ($10 + T)

Deandre has 3 times more Raina =3($10 + T)

substituting the values of Raina and Deandre in Eqn (i) we have

R   +    T    +       D      =$145

($10 + T) +  T  +{3$(10 + T)}=$145

$10 +T   +T+  $30   + 3T    =$145

                     5T   +$40    =  $145

                                5T   =   $145   -  $40

                                 5T     =    $105

                                    T      = $105/5

                                     T     =   $21

i.e  Trey   =  $21

Raina has $10 more than Trey= ($10 + T)

i.e                                               = ($10 + $21)    

                                      Raina  =$31

The cost of plastering the rectangle walls at rate of Rs.15/[tex]m^2[/tex] is Rs.5565.

What is rectangle?

  With four sides, four corners, and four right angles (90°), a rectangle is a closed 2-D object. A rectangle's opposing sides are equal and parallel. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The opposite sides of a quadrilateral are equal and parallel, and all the angles are equal. Around us, there are several rectangle-shaped items. Two dimensions, the length and breadth, define each rectangle shape. The width and length of a rectangle are its longer and shorter sides, respectively.

Given,

Length of room =12m

Breadth of room =10m

Height of room =6m

So, Area of four walls =2(l+b)×h

=>area of four wall=2(12+10)×6=264[tex]m^2[/tex]

Now Area of 2 doors and 3 windows =(2×1×2+3×2×1.5)

Answers

The age of the three brothers, based on the relationship between the ages of Frankenstein, Pugsley, Gomez, is:

Frankenstein - 15 years Pugsley - 12 years Gomez - 7 years

How to find the ages?

Frankenstein is older than Pugsley and so is not the youngest. Pugsley is not the youngest according to the question so Gomez must be the youngest.

Assuming Gomez's age is x, the relationship between their ages is:

Gomez age + Pugsley age + Frankenstein age = 34
x + x + 5 + x + 8 = 34

3x + 13 = 34

x = (34 - 13) / 3

x = 7 years

Pugsley's age is:

The value of the variables in the right triangle are as follows;

[tex]v = \frac{3\sqrt{2} }{2}[/tex][tex]w=\frac{3\sqrt{6} }{2}[/tex]

How to find the side of a right tringle?

A right triangle is a triangle that has one of its angles as 90 degrees.

The side of a right triangle can be found by using trigonometric ratios.

Therefore, let's find the variable length of the right triangle as follows;

sin 30 = opposite / hypotenuse

sin 30 = v / 3√2

1 / 2 = v / 3√2

cross multiply

3√2 = 2v

divide both sides by 2

v = 3√2 / 2

Let's find the variable w.

cos 30 = adjacent  / hypotenuse

cos 30 = w  / 3√2

√3 / 2 = w  / 3√2

cross multiply

√3 × 3√2 = 2w

3√6 = 2w

divide both sides by 2

w = 3√6 / 2

Use the summation formulas to rewrite the expression without the summation notation.

The expression without the summation notation is Sₙ = 4(n² - 1)/n²

How to rewrite an expression without the summation notation?

Summation notation is used to write a very long sum (of elements) in a very concise manner. It is also called Sigma notation

Given:

[tex]\displaystyle \sum\limits_{i = 1}^n \frac{12k(k-1)}{n^{3} }[/tex]

Below are the useful summation formulas you will need in order to rewrite the expression without the summation notation:

[tex]\displaystyle \sum\limits_{i = 1}^n i = \frac{{n\left( {n + 1} \right)}}{2}[/tex]

[tex]\displaystyle \sum\limits_{i = 1}^n {{i^2}} = \frac{{n\left( {n + 1} \right)\left( {2n + 1} \right)}}{6}[/tex]

Where i is a variable

Since 12 and n are constants, we can rewrite the given equation as follows:

[tex]\displaystyle \sum\limits_{i = 1}^n \frac{12k(k-1)}{n^{3} } = \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n k(k-1)[/tex]

                       [tex]= \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n k(k-1)[/tex]

                     [tex]= \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n (k^{2}-k)[/tex]

                    [tex]= \displaystyle \frac{12}{n^{3} } ( \displaystyle\sum\limits_{i = 1}^n k^{2} - \displaystyle\sum\limits_{i = 1}^n k )[/tex]

Using the formula, we have:

                   = 12/n³ ( n(n+1)(2n+1)/6 - n(n+1)/2 )      Factorise n(n+1) out

                   = 12n(n+1)/n³ ( (2n+1)/6 - 1/2 )

                   = 12(n+1)/n² ( (2n+1-3)/2 )

                   = 12(n+1)/n² ( (2n-2/6) )

                   = 2(n+1)/n² (2n-2)

                  =  ( (2n+2)(2n-2) )/n²

                 = (4n² - 4)/n²

                 = 4(n² - 1)/n²

Therefore, using summation formulas to rewrite the expression without the summation notation gives Sₙ = 4(n² - 1)/n²

Jason watched a caterpillar move 10 feet in 2 minutes. Jason says that the caterpillar's unit rate is 0.2 feet per minute, Is Json correct? Explain.

Answers

No, his unit rate would be 5 feet

10/2 =5 feet

5 feet in 1 minute is the unit rate
If the unit rate was 0.2 then the Caterpillar would have moved 0.4 feet in 2 minutes not 10 feet

Rewrite the equation in standard form from vertex form: y = -4(x - 3)² + 6


The equation of the parabola, in standard form is ______________

Answers

y = -4x²+24x-30 is the standard form of parabola whose equation is  y = -4(x - 3)² + 6

What is Parabola?

Parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

The given equation is y = -4(x - 3)² + 6.

We need to write this equation as standard form of parabola.

the equation of a parabola in  standard form is.

y=ax² +bx+c

The given equation should be expanded y = -4(x - 3)² + 6.

y = -4(x²+9-6x)+6

Now apply distributive property

y = -4x²-36+24x+6

y = -4x²+24x+6-36

y = -4x²+24x-30

Hence y = -4x²+24x-30 is the standard form of parabola whose equation is  y = -4(x - 3)² + 6
