Answer two questions about Equations A and B: A. 5 = -2(x-1)
B. 5=-2x + 2
1) How can we get Equation B from Equation A?

You distribute, or open the parenthesis

Step-by-step explanation:

-2 * x = -2x

-2 * -1 = 2

d? maybe

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
