Evaluate the expression by using the given value of the variable.

y ÷ 2 • 4 – 10 ÷ x + 6 where x = 5 and y = 16

a.
36

b.
21

c.
3

d.
–3

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
