Answer:

x=4

Step-by-step explanation:

multiply first eq. by 3 and second by 4 to get rid of y

15x+12y=24

8x-12y=68

add the equations

23x = 92

divide both sides by 23

x=92/23=4

Answer:

x = 4

Step-by-step explanation:

Given the 2 equations

5x + 4y = 8 → (1)

2x - 3y = 17 → (2)

Multiplying (1) by 3 and (2) by 4 then adding will eliminate the y- term

15x + 12y = 24 → (3)

8x - 12y = 68 → (4)

Add (3) and (4) term by term to eliminate y, that is

23x = 92 ( divide both sides by 23 )

x = 4

Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is 12 feet three squares of fluffy material

Hunter-Best [27]

Answer:

4 feet.

Step-by-step explanation:

Please consider the complete question.

Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is filled with 12 cubic feet of fluffy material. The base is 3 ft, the height is 2 ft. What is the length measure?

We know that a wedge is in form of triangular prism, so the volume of wedge will be equal to volume of triangular prism.

$\text{Volume of triangular prism}=\frac{1}{2}(\text{length}\times\text{ width}\times \text{Height})$

Upon substituting our given values in above formula, we will get:

$12\text{ ft}^3=\frac{1}{2}(\text{length}\times3\text{ ft}\times \text{2 ft})$

$12\text{ ft}^3=\text{length}\times3\text{ ft}^2$

$\frac{12\text{ ft}^3}{3\text{ ft}^2}=\frac{\text{length}\times3\text{ ft}^2}{3\text{ ft}^2}$

$4\text{ ft}=\text{length}$

Therefore, the length of the pillow is 4 feet.
