If 5+ 20-22-3x – 10.2-2x + 5, what is the value of x?
-3
-2
2
3

3

Step-by-step explanation:

Step 1: get rid of the +5 on both sides.

Step 2: divide by 10 on both sides

Then you have: 2*2^(2-3x) = 2^(-2x)The factor 2 on the left can be brought into the exponent because you're simply multiplying with 2 more...2^(1+2-3x) = 2^(-2x)Now you can equate the exponents:3-3x = -2x => 3 = -2x+3x => x=3

so D is your answer.

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
