X + y = 56 ------------------(1)
x:y = 5:3
x/y = 5/3
3 x = 5 y
so, x = (5/3)y---------------(2)
sub (2) in (1)
x + y = 56
(5/3)y + y = 56
5 y + 3 y = 168
8 y = 168
y = 168 / 8 = 21
x = (5/3) x 21
= 35
the value of x - y = 35 - 21
= 14

Answer:

- 2 5/12

Step-by-step explanation:

−3 2/3 = x − 1 1/4
x = - 3 2/3 + 1 1/4
x = - 2 - 2/3 + 1/4
x = - 2 - 8/12 + 3/12
x = - 2 - 5/12
x = - 2 5/12

Do cross multiplication.
Convert ounce to pound.
8 ounce is 0.5 lbs
x/0.5 = 17.95/1
