Answer:
x = 35
y = 21
x - y = 14
Step-by-step explanation:
x/y = 5/3 => x = 5y/3
x + y = 56 => 5y/3 + y = 56 => 8y/3 = 56 => y/3 = 7 => y = 21 => x = 56 - 21 = 35 => x- y = 35 - 21 = 14
Answer: The value of x-y is 14.
Step-by-step explanation:
If x:y=5:3 is equal to x+y=56 then you can say that 5/8 of 56 is equal to the value of x and 3/8 of 56 is equal to the value of y.
so x= [tex]\frac{5}{8}*56[/tex]
x = 0.625 * 56
x = 35
And y= 3/8 *56
y= 0.375 *56
y= 21
Check: 35 + 21 =56
Now we know the value of x is 35 and the value of x is 21.
so x- y has to be 35 -21 = 14
