Answer:
y = -5
Step-by-step explanation:
-10(-1/2y + (-7/2)) + 7y = -25
Let's first of all expand the bracket to get;
5y + 35 + 7y = -25
12y + 35 = -25
12y = -25 - 35
12y = -60
y = -60/12
y = -5
The answer for volume would be, 640.
We have an equation: 2*? = 76
⇒ ?= 76/2
⇒ ?= 38
The final answer is 38~
