The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.

san4es73 [151]

Answer:

<h2>16 yards</h2>

Step-by-step explanation:

Given,

Volume of the rectangular prism = 128 cubic yards

Base area of the prism = 8 square yards

Let,

Height of the prism be = h

As we know, 

Base area × height = Volume of the given prism

Therefore, 

By the problem,

=> 8 sq. yd × h = 128 cu. yd

=> 8h = 128

(On dividing 8 from both sides)

$= > \frac{8h}{8} = \frac{128}{8}$

(On Simplification)

=> h = 16

Hence, the height (h) of the prism is 16 yards (Ans)

$3x+2y=-8 1 x - y = -1

Mrac [35]

Answer:

Step-by-step explanation:

in order to solve this system of equation we would say that let

3x+2y=-8........................................................ equation 1

1 x - y = -1 ........................................................ equation 2

from equation 2

1 x - y = -1 ........................................................ equation 2

x = -1 + y....................................... equation 3

substitute for equation 3 in equation 1

3x+2y=-8........................................................ equation 1

3( -1 + y) + 2y = 8

-3 + 3y +2y = 8

collect the like terms

-3 + 5y = 8

5y = 8 + 3

5y = 11

divide both sides by the coefficient of y

5y/5 = 11/5

y = 2.2

put the value y = 2.2 into equation 3

x = -1 + y....................................... equation 3

x = -1 + 2.2

x = 1.2

therefore th value of x is 1.2 and y is 2.2
