Answer:

x = 4

Step-by-step explanation:

RT = RS + ST

RT = 36

RS + ST = 36

6x + 1  + x + 7 = 36

6x + x + 1 + 7 = 36  {Combine like terms}

7x + 8 = 36   {Subtract 8 from both sides}

7x + 8 - 8 = 36 - 8

7x = 28   {Divide both sides by 7}

7x/7 = 28/7

x = 4

Answer:

Step-by-step explanation:

It usually works best for factoring to remove any common factors from the coefficients. Here, they are all even numbers, so have a common factor of 2. After taking that out, you have ...

  2(4x² -4x -3)

To factor this, you are looking for factors of (4)(-3) that have a sum of -4.

  -12 = 1(-12) = 2(-6) = 3(-4)

These pairs have sums of -11, -4, -1. So, we are interested in the factors 2 and -6. We can use those to rewrite the middle term, then factor by pairing.

  = 2(4x² +2x -6x -3) = 2((2x(2x+1) -3(2x+1)) = 2(2x -3)(2x +1)

Of these, the factors that are on your list of choices are ...

Answer:

x = 6

Step-by-step explanation:

We know:

2x - 3 = x +3

Rearrange the equation:

2x - x = 3 + 3

Combine like terms:

1x = 6

Divide:

x = 6

substitute [tex]-6[/tex] in the equation:

[tex]f(x)=x^{2} -4x+5,\\f(-6)=(-6)^{2} -4(-6)+5\\f(-6)=36+24+5\\f(-6)=\boxed{65}[/tex]

Answer:

Step-by-step explanation:

3x + y = 6

4x + 2y = 8

-6x - 2y = -12

4x + 2y = 8

-2x = - 4

x = 2

3(2) + y = 6

6 + y = 6

y = 0

(2,0)

Answer:

30

Step-by-step explanation:

A player answers x correct questions and y incorrect questions for a total of 40 questions.

x + y = 40

The score is obtained by subtracting y incorrect answers from two times the x of correct answers.  The player's score is 50.

2x - y = 50

Use substitution to solve.  Rearrange the first equation so that it is equal to y.  Then, substitute the y-value into the second equation.

x + y = 40

y = 40 - x

2x - y = 50

2x - (40 - x) = 50

2x - 40 + x = 50

3x - 40 = 50

3x = 90

x = 30

Since x was made to represent correct answers, the player had 30 correct answers.

Answer:10.4

Step-by-step explanation:

There are a lot of information's that are already given in the question. Based on these information's the answer can be deduced.

1 mile = 1609 meters

Then

70 miles = 1609 * 70 meters

              = 112630 meters

again

1 hour = 3600 seconds

3 hours = 3600 * 3 seconds

            = 10800 seconds

So

Speed = 112630/10800 meters/second

          = 10.4 meters per second.

So the falcon was flying at a speed of 10.4 meters per second.

Answer:

You can put 1 + 6 into parentheses to make the answer correct.

Step-by-step explanation:

5 × 4 - (1 + 6) = 13

5 × 4 - (7) = 13

20 - (7) = 13

13 = 13

Answer:

5 • 4 - (1+6)=13

Step-by-step explanation:

5 • 4 - 1+6=13

Add parentheses to make this true

5 • 4 - (1+6)=13

Using PEMDAS

Parentheses first

5 • 4 - 7=13

Then multiply

20-7 =13

Then subtract

13=13

Answer:

-6x + 3

Step-by-step explanation:

-3(2x - 1)

We use distributive property

so we mulitply the number that is outside of the paraenthesis (-3), to the numbers on the inside (2x - 1)

-3 × 2x = -6x

-3 × -1 = 3

So we have:

-6x + 3

And we cannot combine them so that is the answer.

Answer and Step-by-step explanation:

Let us assume the number of calls be x

So

For Plan 1

Total monthly charges is $24 for unlimited calls

For Plan 2

There is a charge of $16 and $0.04 per call

We can write as

= 0.04x + $16

a)  Now the inequality equation is

0.04x + $16 > $24

0.04x > $8

x > 200

b)   Now if there are more than 200 calls than Plan 1 is more economical as compared with plan 2

Answer:

F and H

Step-by-step explanation:

From the image attached, the location of the points are E = -9, F = -6, G = -2, H = 6, I = 8. The law of additive inverse states that for a number a, its additive inverse is a number that when added to a equals to zero. This number is usually opposite in sign to a and of the same magnitude i.e -a. The law is given as:

a + (-a) = 0

From the points, F is the additive inverse of H, hence:

F + H = 0

6 + (-6) = 6 - 6 = 0

Hence the two points are F ad H

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.

Given:

UV = 4x, VW = 3x, and UW = 7

UW= UV + VW

7 = 4x + 3x

7 = 7x

x= 7/7

x=1

Hence, UV = 4

Answer:

14 months

Step-by-step explanation:

Here we are interested in calculating the number of months it will take the food kitchen to exhaust the 283,482 soup cans donated to it by a school of it uses 20,000 cans of soup.

This is pretty straightforward, trust me!

What needs to be done here is to simply divide the total number of soup cans donated by the school by the number of soup cans used by the food kitchen each month.

Mathematically, that would be;

283,482/20,000

A calculator would work here? Right?

And the division equals 14.1741

And to the nearest whole number, that is 14.

And yes there would surely be some left, carried over to the 15th month, but would that sustain them for the month? No

Step-by-step explanation:

Answer:

The combined weight of all the basket  is 9 pounds.

Step-by-step explanation:

Given that,

Weight of berries [tex]W=1\dfrac{1}{4}\ pounds[/tex]

[tex]W=\dfrac{5}{4}\ pounds[/tex]

Suppose, The weights of some of their baskets are ,

Weight of first basket with berries = 2 pound

Weight of second basket with berries = 3 pound

Weight of third basket with berries = 4 pound

Weight of fourth basket with berries = 5 pound

We need to calculate the weight of first basket

Using formula for weight

[tex]W_{b}=W_{b+be}-W_{be}[/tex]

Where, [tex]W_{b+be}[/tex] = weight of basket with berries

[tex]W_{b}[/tex] = weight of basket

[tex]W_{be}[/tex] = weight of berries

Put the value into the formula

[tex]W_{b}=2-\dfrac{5}{4}[/tex]

[tex]W_{b}=\dfrac{8-5}{4}[/tex]

[tex]W_{b}=\dfrac{3}{4}\ pounds[/tex]

Similarly,

We need to calculate the weight of second basket

Using formula for weight

[tex]W'_{b}=W_{b+be}-W_{be}[/tex]

Put the value into the formula

[tex]W'_{b}=3-\dfrac{5}{4}[/tex]

[tex]W'_{b}=\dfrac{12-5}{4}[/tex]

[tex]W'_{b}=\dfrac{7}{4}\ pounds[/tex]

We need to calculate the weight of third basket

Using formula for weight

[tex]W''_{b}=W_{b+be}-W_{be}[/tex]

Put the value into the formula

[tex]W_{b}=4-\dfrac{5}{4}[/tex]

[tex]W_{b}=\dfrac{16-5}{4}[/tex]

[tex]W_{b}=\dfrac{11}{4}\ pounds[/tex]

We need to calculate the weight of fourth basket

Using formula for weight

[tex]W_{b}=W_{b+be}-W_{be}[/tex]

Put the value into the formula

[tex]W_{b}=5-\dfrac{5}{4}[/tex]

[tex]W_{b}=\dfrac{20-5}{4}[/tex]

[tex]W_{b}=\dfrac{15}{4}\ pounds[/tex]

We need to calculate the combined weight of all the basket

On adding weight of all basket

[tex]W= W+W'+W''+W'''[/tex]

Put the value into the formula

[tex]W=\dfrac{3}{4}+\dfrac{7}{4}+\dfrac{11}{4}+\dfrac{15}{4}[/tex]

[tex]W=9\ pounds[/tex]

Hence, The combined weight of all the basket  is 9 pounds.
