SOLUTION: If 28C2r=24C2n-4=125:11 find r

Question 945681: If 28C2r=24C2n-4=125:11 find r
Answer by Edwin McCravy(20055) (Show Source): You can put this solution on YOUR website!

If 28C2r=24C2n-4=125:11 find r

That doesn't make any sense.  Is 125:11 a ratio?

Are you given a value for n?  We can't find r if
we don't know n.

Do you mean to have 2 equal signs?

Does 28C2r mean (28C2)r or 28C(2r)?

Does 24C2n-4 mean (24C2)(n-4) or (24C2n)-4 or 24C(2n-4)?
