The sum of twice h and 7 multiplied by 5

10h + 70

Step-by-step explanation:

First you have to look at what your equation is and write it out:

2(h+7) x 5

Then you substitute out and simplify:

10(h+7)

After that, you take out the parenthesis and simplify the rest:

10h + 70

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
