Ben is 5 years older than wendy. ben's age is 11 years less than three times wendy's age. the system below models the relationship between ben's age (b) and wendy's age (w):

b = w + 5 b = 3w – 11

which is the correct method to find ben's and wendy's ages?
solve b + 5 = 3b – 11 to find the value of b.
write the points where the graphs of the equations intersect the x-axis.
write the points where the graphs of the equations intersect the y-axis.
solve w + 5 = 3w – 11 to find the value of w.

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
