2. -33 is your answer
Answer:
x = 16.5
Step-by-step explanation:
2x + 3y = 73.50
5x + 2y = 109.50
(2x + 3y = 73.5) -5
(5x + 2y = 109.5) 2
-10x - 15y = -367.5
10x + 4y =219
-11y = -148.5
y = 13.5
2x + 3(13.5) = 73.50
2x + 40.5 = 73.5
2x = 73.5 - 40.5
2x = 33
x = 16.5
Answer: 8
Step-by-step explanation:
20*.4=8
A cube's volume is length * hight * width
since it is a cube, length hight width are all the same.
so we can use variable x to represent it.
x*x*x
which is

so

cube root both sides
![x = \sqrt[3]{1000} = 10](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B3%5D%7B1000%7D%20%20%3D%2010)
length of its side is 10
