SOLUTION: If y varies directly with x and y = 6 when x = 42 , find y when x =3 If y varies directly with x then y=Kx (6)=K(42) 6/42= K(42)/42 1/7= K REUSE FORMULA y=Kx y=(1/7)(3

Question 162891: If y varies directly with x and y = 6 when x = 42 , find y when x =3
If y varies directly with x then y=Kx
(6)=K(42)
6/42= K(42)/42
1/7= K
REUSE FORMULA
y=Kx
y=(1/7)(3)
y=3/7
