Kala drove 250 miles using 9 gallons of gas. at this rate how many gallons of gas would she need to drive 275 miles
Rus_ich [418]

Answer:

9.9 gallons

Step-by-step explanation:

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

\frac{9}{250}  = \frac{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.

\frac{2,475}{250} =x

9.9 = x

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