The gas tank of your car is 40% full. there are 8 gallons of gas in the tank. what is the capacity of the gas tank? (how many gallons cam your tank hold? ) explain!

8 gal = 0.40 * capacity
(8 gal)/0.40 = capacity = 20 gal

The tank can hold 20 gallons of gas.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
