Question

the variables Y and X have proportional relationship and Y equals 25 when x equals 60 what is the value of x when y equals 30. answer choices X equals 25 x equals 36 x equals 50 x equals 72​

Answer 1

X= 72

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!
