Answer :

The combined weight of the motorcycle and gasoline in the gas tank when the gas tank contains 5 gallons of gas is 401.5 pounds.

Weight of one gallon of gas = 6.3 pounds

Weight of 2.6 gallons of gas = 6.3×2.6

Performing multiplication

Weight of 2.6 gallons of gas = 16.38 pounds

Total weight = weight of motorcycle + weight of 2.6 gallons of gas

386.38 = Weight of motorcycle + 16.38

Weight of motorcycle = 386.38 - 16.38

Weight of motorcycle = 370 pounds

Weight of 5 gallons of gas = 6.3 × 5

Performing multiplication

Weight of 5 gallons of gas = 31.5 pounds

Total weight = 370 + 31.5

Performing addition

Total weight = 401.5 pounds

The combined weight is 401.5 pounds.
