Answer:

X= 72

Step-by-step explanation:

1.Find the constant proportionality (r) in y=rx

so when Y= 25 X=60 find (r)

2. Plug in information that is given to solve in the formula y=rx

y=rx

25=60r

3. Solve

divide both side by 60

r=25/60 or 0.416 with 6 repeating

4. Now you know what (r) is you can use the formula to find the value of x

30=0.416x with 6 repeating

x= 30/0.416 with 6 repeating

x=72

Hope this help you!
