Rewrite in simplest terms: (-8x – 9y) + (-X – 5y)

-9x - 14y

Step-by-step explanation:

Step 1: Write expression

(-8x - 9y) + (-x - 5y)

Step 2: Combine like terms

-9x - 14y

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
