Given: 5 > x + 7.

choose the solution set.

{x | x r, x > -2}
{x | x r, x < -2}
{x | x r, x > 2}
{x | x r, x < 2}

x is less than negative 2

Step-by-step explanation:

Using the properties of addition, we move the 7 over to the five, making it negative.

This makes negative 2 because we subtract 7 from 5.

Then, we can flip the equation to understand it better, making the x in the front.

This makes the final solution x is less than -2

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
