What is the answer to question 12?

x = 10

Step-by-step explanation:

30 - x/ 10= 2

10 ( 30 -x)/10 = 2 * 10

30 - x = 20 Simplify

Subtract 30 from both sides

30 - x - 30 = 20 - 30

Simplify - x = - 10 the divide both sides by -1

x = 10

Good luck

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
