Option B, 24 feet

Step-by-step explanation:

<u>Step 1: Determine the perimeter</u>

To find how much fence we will need to go around the garden means that we need to find the perimeter. In order to find the perimeter we need to add up all of the sides which we can do using the formula below.

$P = 2(w + l)$

$P = 2(5\ ft + 7\ ft)$

$P = 2(12\ ft)$

$P = 24\ ft$

Answer: Option B, 24 feet

Model Cars, Inc. makes red cars, white cars, and blue cars. The profit on a blue car is $10 more than the profit on a white car.

tekilochka [14]

Answer:

Let b = profit on a blue car

w = profit on a white car

r = profit on a red car

b = w + 10 (1)

r = w - 7 (2)

2r = b -2

2r-b= -2 (3)

Subtract eq. (2) by 2q. (1)

r - b = 0 - 7 - 10

r - b = -17 (4)

Subtract eq. (3) by eq. (4)

r - 0 = -2 - (-17)

r = 15

in eq (2)

r = w - 7

15 = w - 7

w = 22

in eq (1)

b = w + 10

b = 22 + 10

b = 32

The profit on a blue car is $32

Step-by-step explanation:

THE ANSWER IS 32

Five yards of material is needed to make

Mkey [24]

Answer:

The y-coordinate would be 17.5

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

y ----->material needed in yards

x ----> number of curtains

we know that

For y=5, x=2

Find the value of the constant of proportionality k

$k=y/x$

substitute the given values of x and y

$k=\frac{5}{2}=2.5$

The linear equation is equal to

$y=2.5x$

If the x-coordinate was 7

then

substitute in the equation x=7 and solve for y

$y=2.5(7)$

$y=17.5$

therefore

The y-coordinate would be 17.5
