The gas gauge in a car shows it has 40% of a tank of gas. if the car has about 5 gallons, approximately how many gallons can the tank hold when it is full?

the tank can hold 12.5 gallons when it is full

Step-by-step explanation:

Let's assume

tank can hold 'x' gallons when it is full

we are given

The gas gauge in a car shows it has 40% of a tank of gas

So, gas in car is

and we have

the car has about 5 gallons

so, we can set it equal

and then we can solve for x

Multiply both sides 5

we get

So, the tank can hold 12.5 gallons when it is full

the answer is a

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
