Answer: x=20
Step-by-step explanation:
63-x=2x+3
-x-2x+63=3
-x-2x=3-63
-3x=3-63
-3x=-60
-3x/3=-60/3
X=20

Answer:
48
Step-by-step explanation:
We have that the volume of a cylinder is given by:
V = pi * (r ^ 2) * h
In this case we know the diameter, we know that the radius is half the diameter like this:
r = d / 2
r = 8/2
r = 4
Now we know that the V equals 768 pi
we replace and we have:
768 * pi = pi * (4 ^ 2) * h
768 = 16 * h
h = 768/16
h = 48
Therefore the value of x would be 48 cm
