Look at the picture.

x + 2x = 12

3x = 12 <em>divide both sides by 3</em>

x = 4

AB = 12 + x

therefore AB = 12 + 4 = 16

<h3>Answer: AB = 16.</h3>

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.
