Heath Carey · Answer 1

Answer:14

Step-by-step explanation:

x+y=56

x:y=5:3

Sum of ratio=5+3

Sum of ratio=8

x=5/8x56

x = (5x56) ➗ 8

x=280 ➗ 8

x=35

y=3/8x56

y = (3x56) ➗ 8

y=168 ➗ 8

y=21

x-y

35-21=14

x-y=14

Reuben Holmes · Answer 2

x - y = 14

Step-by-step explanation:

x/y = 5/3 = > x = 5y/3

x + y = 56

5y/3 + ³⁾y = ³⁾56

5y + 3y = 3*56

6y = 168

y = 168 : 8

y = 21

x = 5*21/3 = 105/3 = 35

x - y = 35 - 21 = 14
