Answer:
x = 16
Step-by-step explanation:
12(x - 20) = -48
Use distributive property
12*x - 12*20 = -48
12x - 240 = -48
Add 240 to both sides
12x = -48 + 240
12x = 192
Divide both sides by 12
x = 192/12
x = 16

The number are repeated forever is not rational number
Answer:
706.85775
Step-by-step explanation:
First you find the volume of the tank
13*3.14159=40.84067
40.84067*75=3063.05025
Then find the volume of both the tank and sleeve
13+3=16
16*3.14159=50.26544
50.26544*75=3769.908
Subtract the original volume with the combined volume
3769.908-3063.05025=706.85775
