Question

The value of y is directly proportional to the value of x. If y = 3 whenx = 7, what is the value of x when y= 10.5? *Hint: Now you are looking for the "X". (show work)

Answer 1

we have that y=k*x, therefore we can say that k=y/x

`k=(3)/(7)`

so, if we have y= 10.5 we get that

`x=(y)/(k)=(10.5)/((3)/(7))=24.5`

x=24.5
