By how much is -20 less than 20

40

Step-by-step explanation:

20 - 40 = -20

Using zero as a reference point 20 is 20 units above zero and -20 is 20 units below zero.

20 + 20 = 40

-20 and 20 are 40 units away from each other.

-20 is 40 less than 20

the probability is 0

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
