Question

variables y and x have a proportional relationship, and y = 15 when x = 3. What is the value of x when y = 4? Enter your answer in the box. x =

Answer 1

Answer:

x=0.2

Step-by-step explanation:

We have been given that variables y and x have a proportional relationship, therefore, we can represent this information as:

$y=kx$, where k is proportionality constant.

Let us find our proportionality constant by substituting x=3 and y=15 in our above equation.

$15=k\cdot 3$

$k=\frac{15}{3}$

$k=5$  

Now we will substitute k=5 and y=4 in our equation to find the value of x.

$4=5\cdot x$    

$x=\frac{4}{5}$  

$x=0.2$

Therefore, the value of x will be 0.2.
