Answer:
y = 3
x = 2
Step-by-step explanation:
x+y=5 == -2x - 2y = -10
2x-y = 1 == 2x - y = 1 +
-------------------
-3y = -9
<u>y = 3</u>
x + y = 5
x + 3 = 5
<u>x = 2</u>

Answer:
The radius is 4.097396898
Step-by-step explanation:
A hemisphere is 1/2 of a sphere so the volume is 1/2 of the volume
V = 1/2 ( 4/3 pi r^3)
= 2/3 pi r^3
144 = 2/3 pi r^3
Multiply each side by 3/2
3/2 *144 = 3/2 * 2/3 pi r^3
216 = pi r^3
Divide each side by pi
216/ pi = pi r^3/pi
68.78980892 = r^3
Take the cube root of each side
(68.78980892 )^1/3= (r^3)^1/3
4.097396898 = r
The radius is 4.097396898
