I give brainliest Which of the following sets of ordered pairs represent functions? Select all.

A. (0,3), (1,4), (2,5), (1,6), (0,7)

B.(-2,0), (0.1), (2.2), (4,3), (6,4)

C. (2,4), (0,2), (2,0). (0,-2), (2,-4)

D. (3,-2), (4, -3), (5,-4), (6,-5)

E. (3,-2).(-2,3), (4, -1) (-1, 4)

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
