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 =

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:

, where k is proportionality constant.

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

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

Therefore, the value of x will be 0.2.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
