Which expression best represents the difference between triple a number and double a number? a) 3x - 2x eliminate b) 2x - 3x c) x3 - x2 d) x2 - x3

3x-2x (^:

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

hope this you

all it means is function 3
