you are running a fuel economy study one of the cars you find blue can travel 39 1/2 miles on 1 1/4 gallons of gasoline another cars red can travel 22 2/5 miles on 4/5 gallons of gasoline what is the unit rate for miles per gallon for each car which car can travel the greater distance from 1 gallon of gasoline

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Is the figure congruent? yes or no?
