Lesson #17 Bridgette has several watermelons. If she puts 35 pounds of watermelons on
the see-saw, how much weight should be added to the left side to balance the
the right side of the see-saw, and 26 pounds of watermelons on the left side of
see-saw? Write and solve an equation where w is the extra weight.

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

factor trees are nice.
