If x:y=7:5, then (5x-2y):(3x+2y)= ?
Read Solution (Total 6)
-
- 25/31 ans.
sol:-
x=7y/5
so putting the value of x we get:
{5*5y}/{(21+10)*y}=25/31=25:31 ans. - 12 years agoHelpfull: Yes(16) No(0)
- 25:31
(5x-2y)/(3x+2y)
x= y*7/5
putting bthis value , we get
(5x-2y)/(3x+2y) = 25/31

- x:y=7:5 therefore x=7,y=5
(5x-2y):(3x+2y)=(5*7-2*5):(3*7+2*5)
=(35-10):(21+10)
=25:31 - 11 years agoHelpfull: Yes(2) No(0)
- 39 : 31
(5x-2y)/(3x+2y)
x= y*7/5
when we will put this value.
we will get (49y-10y/5)/(21y+10y/5)=39:31 (Ans) - 12 years agoHelpfull: Yes(0) No(11)
- assume x=7 y=5 ans rest u all know
ans=25:31

- x:y=7:5
x/y=7/5
5x-2y/3x+2y=5(x/y)-2/3(x/y)+2
5(7/5)-2/3(7/5)+2
=25/31 - 8 years agoHelpfull: Yes(0) No(0)
