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)

Respuesta :

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

[tex]k=\frac{3}{7}[/tex]

so, if we have y= 10.5 we get that

[tex]x=\frac{y}{k}=\frac{10.5}{\frac{3}{7}}=24.5[/tex]

x=24.5
