X:y=5:3 and x+y=56
work out he value of x-y
2 answers:
Answer:
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
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
