Simplify the expression and solve the equation. show all calculations

First of all, we can observe that

Then, we can rationalize the denominator by using the formula

If we multiply both numerator and denominator by [/tex]\sqrt{8}+3[/tex] we have

We can also observe that

And the expression simplifies into

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

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
