A factory stores natural gas for its backup generator in a pressurized steel tank. The tank is shaped like a sphere and has an inner radius of eight meters. Calculate the volume of the tank, then answer me this: If the backup generator burns the natural gas at a rate of two cubic meters per minute, how long can the generator run before it runs out of natural gas?

As long as there is a fuel supply of natural gas or propane, a well-maintained backup generator will keep running. If the Generac generator is running on propane, with a 500-gallon tank, it should run 24 hours a day for over a week.

Step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
