Question

3) If x : y =4:7, find [4x + 5y] [5x +3y]​

Answer 1

Answer:

x/y=3/4  (4x+5y)/(5x+2y) = (4( x/y)+5)/(5 (x/y)-2) = (4(3/4)+5)/(5(3/4)-2)  =(3+5)/(7/4)  = 32/7 /445897/if-x-y-3-4-find-4x-5y-5x-2y

Step-by-step explanation:

Hii

How are you

Answer 2

51/41

Step-by-step explanation:

x/y=4/7

x=4y/7

4x+5y=16y/7+5y=51y/7

5x+3y =20y/7+3y =41y/7

(51y/7)/(41y/7)

=51/41
