Step-by-step explanation:

Here you go mate

Step 1

8.6(x – 1) + 8x  Equation/Question

Step 2

8.6(x-1) + 8x  Simplify

8.6x+-8.6+8x

Step 3

8.6x+-8.6+8x  Combine the terms

(8.6x+8x)+(-8.6)

Step 4

(8.6x+8x)+(-8.6)   Add them

Answer

16.6x-8.6

Hope this helps

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
