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:
x=15
Step-by-step explanation:
Since the little square next to A has been cut in half we know that 3x = 1/2 of 90:
3x=45
Divide both sides by 3:
3x÷3=45÷3
x=15
