A group of college students is volunteering for homes for the community during their spring break. They are putting finishing touches on a house they built. Working alone, Wade can paint a certain room in 7 hours. Rhonda can paint the same room in 5 hours. How long will it take them working together to paint the room? Round your answer to the nearest hundredth if necessary
@lgbasallote i think you solved one of these yesterday
can you please helpp me
well that guy had a formula. what math are you in?
i dont think i did
algebra 1 trying to pass it this is like my last section of the chapter and if i pass it i pass algebra and go to geometry so i would appreciate your help
oh really. well it must've been someone yesterday. i just cant remember the formula
you gotta remember. for simtran's sake!! she would appreciate *your* help after all
ok i found the formula http://prepfortests.com/gmat/tutorials/rates/combinedworkformula
so t1 = 7, t2= 5 1/7 + 1/5 = 1/t
@Igbasallote lol i would apreciate it.... @Lethal i dont understand formulas
aw bummer @Lethal looks like you have to do this without a formula :(
so how many hours would it be then?
its simple. all you have to do is 1/7 + 1/5
i honestly dont understand this stufff.........
how has your teacher taught it? didn't she teach the formula?
know i have never learned this should i upload a file up for you to see the answers?
no, the answer should be 35/15 hours
which is also 7/3
let me guess @simtran you're from an online school right?
and btw @Lethal it's not 35/15 ...i just thought you should know...
lgbas is pretty smart from what i've seen.
noo i just took algebra because i failed it second semester so can you please helpp me
no he isnt. he just blabbers random stuff and people instantly believe him
Here is it
oh wow well its 35/12 which is 2.92 i accidentally put 35/15 when i got the right answer
Thanks you i have more questions if you could help me that would be great
haha well i should get off this till i do my own homework.
he'll be glad to help!
..... -_-
mwahaha
where do you guys livee at?
lgbasallote can help, he knows.
I'm in Arizona. where it's hot.
do you guys know this question?
do you know anything?
Yes, i do.
i know that x = -4/5 but if you failed algebra you really should understand it because your gonna be usuing it all throughout your high school math years.
i tried doing it and i somehow ended up with the wrong answer
Here another one i dont understand
