2) If -5 +4x = 6x, then 4x = ?
A) 5/2
B)-10
C)-5/2
D)-20

Work Shown:

-5 + 4x = 6x

-5 + 4x - 4x = 6x - 4x ... subtract 4x from both sides

-5 = 2x

2x = -5

2*2x = 2(-5) ... multiply both sides by 2, see note below

4x = -10

note: Alternatively, you can solve 2x = -5 for x to get x = -5/2, then multiply both sides by 4 to end up with 4x = -10.

Step-by-step explanation:

-5 +4x = 6x

add5 : -5 +4x+5 = 6x+5

4x= 6x+5

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
