Solve for x. 4 x plus 1 equals 9 a. -2 b. 2 c. 3 d. -3

B.2

Step-by-step explanation:

4x + 1 = 9

4x + 1 -1 = 9-1

4x=8

8/4=2

for b its (t) and c its (d)

step-by-step explanation:

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
