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
Since both equations are equal to ‘m’ plug it in! 6h+15=8h+9 *now simplify by adding and subtracting likes from one side to another* 6=2h *now divide both sides by 2* 3=h; Nolan and Claire will have the same amount of money after 3 hours
