The easiest way would be adding 76
V=4/3pi(r^3)
V=4/3pi(9^3)
V=3,054 inches^3
Think this is right
For this case we must simplify the following expression:

We have that by definition of properties of powers that is fulfilled:

Then, rewriting the expression:

Answer:

Answer:
x=1/2, y=2;
Step-by-step explanation:
First pair:
2x-5y =-9
4x+5y=12
Add them together:
6x=3
x = 1/2
2(1/2) - 5y =-9
1-5y = -9
1+9=5y
y=10/5=2
U had to take a pic of the work so we could see it
