elijah has a flower box in the shape of a rectangular prism with interior dimensions that are 15 inches in length 8 inches in height elijah will fill the flower box three fourth full of soil. how many cubic inches of soil will be in the flower box

the amount of soil needed is

Step-by-step explanation:

N/B: the width is 8 in

this problem bothers on the mensuration of solid shapes, rectangular prism

Given data

length l= 15 in

width w= 8 in

height h= 3/4 in

The amount of soil need in the flower box is equivalent to the volume of the box for the given data.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
