Question
Y varies direct proportion with x.if x=5 then y=12,thus find the value of y when x=7.5
Answers

y =kx , where k is a constant
given: x=5 , when y = 12
12 = 5k
k = 12/5
so y = (12/5)x
when x = 7.5
y = (12/5)(7.5) = 18
given: x=5 , when y = 12
12 = 5k
k = 12/5
so y = (12/5)x
when x = 7.5
y = (12/5)(7.5) = 18

X=ky
X=5 y=12
So
Y=when x=7.5
5/7.5×12/y
5y/5=93.6/5
Y=18.72
X=5 y=12
So
Y=when x=7.5
5/7.5×12/y
5y/5=93.6/5
Y=18.72
