Answer:

x= 13

Step-by-step explanation:

3x-4+20= 55

combine like terms:

3x+16= 55

subtract 16 from both sides:

3x = 39

divide 3 to both sides:

x= 13

Answer:

12

Step-by-step explanation:

We want the smallest possible number that can be divided by both 4 and 6 with no remainders.

12 is the least common multiple (LCM) of both 4 and 6, meaning it's the smallest number that 4 and 6 both divide into evenly.

24 could be used as a common denominator, but it isn't the least common denominator. It has more prime factors than is necessary to be the LCD.

12, when its prime factorization is written out, is 2² • 3.

24, when its prime factorization is written out, is 2³ • 3.

9/4 → (9•3)/(4•3) → 27/12

5/6 → (5•2)/(6•2) → 10/12

Answer:

the number is 33

Step-by-step explanation:

x-9=24

x=33

The number is 33

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be x

The number when decreased by 9 , the result is 24

So , x - 9 = 24

Adding 9 on both sides , we get

x = 33

Hence , the number is 33

Answer:

2 x ? = 7 1/2 and ? x 2 = 7 1/2

Step-by-step explanation:

This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.

I know this might not be the best step-by-step explanation ever but I truly tried but the answer is correct.

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex].

Where,

Answer:

divde 81/3 to find 27

Step-by-step explanation:

The mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction can also be an ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

A mixed fraction is one that has both a quotient and a remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder.

Given mixed fraction is 8 ( 1 / 3 ). The fraction will be solved by multiplying the whole number with the denominator and adding the numerator.

8 ( 1/3 ) = ( 24 + 1 ) / 3  

8 ( 1/3 ) = ( 25 ) / 3  

Therefore, the mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).

Answer:

Part A:

Option A is a linear function

Part B:

a(t) = t × 100 + 1000

Part C:

Option B is an exponential function

Part D

[tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]

Part E:

There will be a significant difference in the value of Bridget's investment after 20 yeas if she uses Option A over Option B

Step-by-step explanation:

The given parameters are;

The amount Bridgette has to invest = $1,000

The value of each investment option is given as follows;

Number of years   [tex]{}[/tex]    Option A    [tex]{}[/tex]     Option B

1                               [tex]{}[/tex]    1100                 1100

2                               [tex]{}[/tex]   1200                1210

3                              [tex]{}[/tex]    1300                1331

Part A:

Given that the first difference between subsequent data values are 2 - 1 = 1 and 1200 - 1100 = 100, 3 - 2 = 1 and 1300 - 1200 = 100 both of which are constant, the type of function that would be best to describe option A is a linear function

Part B:

The function a(t) for Option A is given as follows;

The rate of change of the function amount with time is (1300 - 1200)/(3 - 2) = 100

Therefore, comparing with the general form of a linear function, y = m·x + c, we have;

m = The rate of change of the function = 100

The y-intercept, the value of the amount a 0 time (the start of the investment) = c = 1000

The function in terms of t, a(t) = t × 100 + 1000

Part C:

The first difference of Option B are different but the first ratio given as follows;

1210/1100 = 1331/1210 = 1.1 = Constant which is the characteristics of an exponential variable

Therefore, the equation to describe the value of the investment in dollars, of Option B is an exponential function

Part D

We, have for an exponential function;

[tex]b(t) = 1000 \times (1 + r)^t[/tex]

When t = 1, we have;

[tex]b(1) = 1000 \times (1 + r)^1 = 1100[/tex]

∴ 1 + r = 1100/1000 = 1.1

r = 1.1 - 1 = 0.1

We check for t = 2, to get;

[tex]a(2) = 1000 \times (1 + 0.1)^2 = 1210[/tex]

We check for t = 3, to get;

[tex]b(3) = 1000 \times (1 + 0.1)^3 = 1331[/tex]

The function b(t) to describe the value of the investment in dollars, of Option B after t years is [tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]

Part E:

The investment value after 20 years is given as follows;

For Option A, we have;

a(20) = 20 × 100 + 1000 = 3000

For Option B, we have;

[tex]b(20) = 1000 \times (1 + 0.1)^{20} \approx 6727.5[/tex]

Therefore, the difference in the investment value after 20 years for Option B and Option A is approximately $6727.5 - $3000 = $3727.5 which is significant.

Step-by-step explanation:

So because Howard wants to divide the granola evenly among all of his friends, we have to divide the amount of pounds he has by the number of friends he has.

(3/5) / 4

Dividing by four is the same as multiplying by the reciprocal of 4 which is 1/4.

So (3/5) * (1/4) is 3/20 which is .15 pounds

Answer:

1) Measure angle QWT and TWX are complementary because their measures add up to 90 degrees.

2) Both measure angles add up to 90 degrees because they're complementary.

3) Angle QWT = 2x and angle TWX = x + 6, and since angles QWT + TWX = 90 then 2x + x + 6 = 90.

4) (Made up?:) Angle measure QWX = 90. The quarter-turn, or the small square, indicates that the angle is 90 degrees.

5) (?)

6) x = 28 because it fulfills the equation, 2x + x + 6 = 90, or 3x + 6 = 90. 90 - 6 is 84, and 84/3 is 28.

Step-by-step explanation:

Since C represents the cost, and Allie's parents are willing to spend $300 for the party, our equation will now look like this:

300=5p+215

we are trying to find out how many people will able to attend

300=5p+215

-215        -215

---------------------

85 =  5p

divide by 5 on both sides to undo the multiplication (5p)

300=5p+215

-215        -215

---------------------

85 =  5p

÷5 =  ÷5

--------------

17  = p

So, p (number of people attending) would be 17 :)

Answer:

840 has 6 odd factors

Step-by-step explanation:

Answer:

{x,y}={31,4}

Step-by-step explanation:

x-8y = -1  x-6y = 7

Answer:

first we find the value of 'y' so

x-8y=-10+8y

x=-10+8y

-2(-10+8y)-6y=-24

20-16y-6y=-24

20-22y=-24-20

-22y=-44

y=2

then also we can find the value of 'x'

-2x-6y=-24

2x-6(2)=-24

2x-12= -24

2x= -24+12

x= -12
