Answer 2

do you know how?

Answer 3

@Cardinal_Carlo

Answer 4

Yes. It's basically like this:
\[\frac{ 1 }{ x } + \frac{ 1 }{ x + 8 } = \frac{ 1 }{ 3 }\]
\[\frac{ (x + 8) + x }{ x(x + 8) } = \frac{ 1 }{ 3 }\]
\[\frac{ x ^{2} + 8x }{ 2x + 8 } = 3\]
\[x ^{2} + 8x = 3(2x + 8)\]
\[x ^{2} + 8x = 6x + 24\]
\[x ^{2} + 2x - 24 = 0\]
\[(x + 6)(x - 4) = 0\]
\[x = 4 ~~and ~~x = -6\]
However, time cannot be negative so we only accept x = 4 which is Harry's rate of 4 hours per job. And since Jimmy is 8 hours slower, he has a rate of 12 hours per rake job.
\[4 + jimmy = 8\]
\[jimmy = 12\]


I apologize for taking so long, had trouble with the syntax in the Equation button.

Answer 5

no, thank you so much for your help! @Cardinal_Carlo IN all realness haha how did you get to be so good at math? I just need to know because I need to get really good at it!

Answer 6

Always be curious, and always try to satiate that curiosity. You haven't yet the slightest clue of what you could've possibly learned.
