Andy records a temperature decrease of 37°F over 4 1/2 hours. The temperature decreased the same number of degrees each hour. Which expression can Andy use to find the change in temperature each hour?

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

answer: i think it is (1,-2)

what is the rest of the question? ?
