Best ResponseYou've already chosen the best response.0Harry can rake the leaves in the yard 8 hours faster than his little brother Jimmy can. If they work together, they can complete the job in 3 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Jimmy to complete this job on his own.

Best ResponseYou've already chosen the best response.1x = time it takes Jimmy to do the job alone x8 = time it takes Harry to do the job alone (since he can do it 8 hrs faster) you can form this equation based off of the given word problem \[\Large \frac{1}{x} + \frac{1}{x8} = \frac{1}{3}\] solve for x to get your answer

Best ResponseYou've already chosen the best response.1\[\Large \frac{1}{x} + \frac{1}{x8} = \frac{1}{3}\] \[\Large 3x(x8)*\left(\frac{1}{x} + \frac{1}{x8}\right) = 3x(x8)*\left(\frac{1}{3}\right)\] \[\Large 3x(x8)*\left(\frac{1}{x}\right) + 3x(x8)*\left(\frac{1}{x8}\right) = 3x(x8)*\left(\frac{1}{3}\right)\] \[\Large 3(x8) + 3x = x(x8)\] I'll let you take over

Best ResponseYou've already chosen the best response.1In step 2, I multiply both sides of the equation by the LCD 3x(x8) to clear out all the fractions (which are fully cleared out by step 4)

Best ResponseYou've already chosen the best response.1oh sorry line 3 is cut off, it is supposed to be \[3x(x8)*\left(\frac{1}{x}\right) + 3x(x8)*\left(\frac{1}{x8}\right) = 3x(x8)*\left(\frac{1}{3}\right)\]
