You are running a fuel economy study. One of the cars you find is blue. It can travel on
of gasoline. Another car is red. It can travel
on
of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on of gasoline?
The unit rate for the blue car is
nothing mile(s) per gallon.
(Simplify your answer. Type an integer, proper fraction, or mixed number.)

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

stops on an even number.

4y - 6 + y^2 - 9 = y^2 + 4y - 15
