Which of the following equations is equivalent to 4.12x + 5.2 = 8.23? (1) 412x + 52 = 823 (2) 412x + 520 = 823 (3) 9.32x = 8.23 (4) 0.412 + 0.52 = 8.23 --- please help

(2) 412x + 520 = 823

Step-by-step explanation:

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
