Any help with this question:

Tom files a paper in 's' minutes

Paco in 's-2'

and Carl in 's+1' minutes

when tom and paco work together it takes them 1 minute and 20 seconds

when paco and carl work together it takes 1 minute and 30 seconds

how long does it take for each of them to file a paper?

the answer in the book is s= 4 but i keep getting 3...

i like the low ones... which design do you like the best?

white, black and red or black and gold?

thanks

so i have no idea how to get the answer the book has to this question:

machine A can fill a box of chocolates in 's' minutes and machine B fills and identical box in 's+10' minutes

when they work together, they can fill a box in 15 minutes

how long does each machine take to fill a box on its own?

if possible, can you give the equation and a breakdown of the steps?

and the answer in the book says that s= 25.8

so A is 25.8 minutes and B is 35.8 mins

the book could be wrong though! it's happened before

thanks for your time

just look at it!!

whose life is now complete?!?

Billie Joe on piano and a singing dog... way better than a lot of pop music out there!

can't wait for this to go viral...

so I'm 16 and I've never had any singing training but I've played music since i was 5 and i am not tone deaf.

i can hit notes that i hear but i'm looking for a way to expand my range a bit and make my voice stronger because after a while it starts to feel strained

if you could recommend any videos or exercises you have to correct these problems that would be great!!

as well, is it possible to do this myself because i don't have money for singing lessons...

im not looking to be super pro, just enough to not feel uber awkward lol

thanks!
