Substitute w = 1 and w = 3 to determine if the two expressions are equivalent 4 (3w + 4) 16w + 12

Expressions are not equivalent

Step-by-step explanation:

Given expressions are:

Putting w=1 in both expressions

Both expression have value 28 on w=1

Putting w=3 in both expressions

Both expression have different values at w=3

Hence, in order for the expressions to be equivalent they both should produce same value on w=3 too.

So, it can be concluded that both expressions are not equivalent ..

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
