- x : y = 5 : 3 then (8x-5y) : (8x+5y)=?
=( (8*5) - (5*3) ) : ( (8*5) + (5*3) )
= (40-15) : (40+15)
divided by 5 on both side below the value
=25 : 55
= 5 : 11 - 8 years agoHelpfull: Yes(0) No(0)
- Let x,y=5k,3k
Now(8x-5y):(8x+5y)=(8*5k-5*3k):(8*5k+5*3k)
(40k-15k):(40k+15k)=25k:55k=5:11 - 3 years agoHelpfull: Yes(0) No(0)
