Question

Kala drove 250 miles using 9 gallons of gas. at this rate how many gallons of gas would she need to drive 275 miles

​

Answer 1

9.9 gallons

Explanation:

To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

`(9)/(250) = (x)/(275)`

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.

`250(x) = 250x\\`

`275(9) = 2,475`

Now, lets put the values above back into the equation:

`250x = 2,475`

Lets solve this equation. First we divide 2,475 by 250, making x by itself.

`(2,475)/(250) =x`

`9.9 = x`

This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.
