Question

Sally can paint a room in 6 hours while Steve can paint the same room in 7 hours. How long will it take if they paint the room together?

Answer 1

t=t1t2/(t1+t2)

Answer 2

Let x=the hours it would take to paint together

Answer 3

so how would you set up the equation?? I'm so bad at that part sorry

Answer 4

Solve for x, get the time for team work.

Answer 5

So,
Sally paints how much of the room in x hours?

Answer 6

\[\frac16+\frac17=\frac 1x\]Sorry did a typo hehe.

Answer 7

x/6...

AND Steve would paint x/7

So you can say \[\large \frac x6+\frac x7=1\]

Answer 8

I got it, thank you!
