Woman wants to remodel her bathroom. Materials will cost her $500 and the contractor charges $40 per hour. The equation y = 40x + 500 represents the amount of money needed for x number of hours worked by the contractor. How much money would it cost if it took the contractor 12 hours to completely remodel her bathroom?

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?

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3
