Answer:

x=4, y=2

Step-by-step explanation:

2x - y = 6

x + y = 6

Add these together to eliminate y

2x - y = 6

x + y = 6

-----------------

3x = 12

Divide by 3

3x/3 = 12/3

x=4

But we still need y

x+y =6

4+y =6

Subtract 4 from each side

4+y-4 = 6-4

y=2

Find the height of the figure below if the volume is 480.66 cm^3.

salantis [7]

$V=\pi r^{2}h\\ 480.66=\pi 6^{2} h\\first, divide both sides by \pi:\\153=6^{2}h\\153=36h\\divide both sides by 36:\\4.25=h$
