Question

At the start of a trip, a car's gas tank contains 12 gallons of gasoline. During the trip, the car consumes

gallons of gasoline. How much gasoline is left in the tank?

Answer 1

12-g= amount of gas used

Explanation:

g equals gallons

Answer 2

`\text{ Amount of gasoline left in car} = 12 - x`

Explanation:

We are given the following information in the question:

Amount of gasoline in car's tank = 12 Gallons

Let
`x` be the amount of gasoline consumed by car during the trip.

Then, we can express the amount of gasoline left in car's tank with the help of an algebraic equation.

`\text{ Amount of gasoline left in car}\\=\text{Total amount of Gasoline }-\text{ Amount of gasoline consumed by car during trip}\\`

Thus,

`\text{ Amount of gasoline left in car} = 12 - x`

Example:

if x = 4 that is amount of gasoline used during trip is 4 then amount of gasoline left in car tank is
`12 - 4 = 8 \text{Gallons}`
