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

avanturin [10]

Answer:

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

$=\frac{40}{100}\times x$

and we have

the car has about 5 gallons

so, we can set it equal

and then we can solve for x

$5=\frac{40}{100}\times x$

$5=\frac{4}{10}\times x$

$5=\frac{2}{5}\times x$

Multiply both sides 5

$5\times 5=5\times \frac{2}{5}\times x$

$5\times 5=2x$

$25=2x$

we get

$x=12.5$

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