Answer 65 and 85 minutes Reason We know he exercised for 2 days We know the second day was -20 We know the total minutes = 150 We don’t know x
Equation is 2x -20 = 150. Solve for x Isolate x by subtracting (-20) from both sides. 2x = 170. Solve for x by dividing both sides by 2. X= 85 Now we know the first day was (-20) 85-20= 65
For two rectangles to be similar, their sides have to be proportional (form equal ratios). The ratio of the two longer sides should equal the ratio of the two shorter sides.
