Four-thirds times the sun of a number and 8 is 24.what is the number

So, it seems like your unknown number "x" = 10.

Step-by-step explanation:

You start by making an equation:

() × (x + 8) = 24

You now know that 24 - 8 = 18. Subtract that again and 18 - 8 = 10.

That means that since since we know subtracted four-thirds of the sum,

x = 10.

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
