4 = (r-2) t
8 = (r+2) t
4 = (r-2) * [8/(r+2)]
4 = (8r-16)/ (r+2) . . .multiply by 2
4r + 8 = 8r - 16
4r = 24
r = 6
hope this helps
All you need to do is simplify 5-8 and it doesn't simplify any more so your ratio would be 5 to 8
I think is is:
7/20=35/100=0.35=35%
Hope I'm not wrong!
Hope this helps! :D
First, you have to wait until 2 people answer your question. When you finally see 2 people, a crown will pop up on your browser. Then pick which ever person you want or the best answer. That's all you have to do.
