Y and x have a proportional relationship, and y = 12 when x = 5. What is the value of y when x = 8?

Enter your answer in the box.

19.2 is the ancewer

...

Y = kx < - - direct variation

Step 1: find k by plugging in given x and y and then solving.

12 = 5k

12/5 = k

2.4 = k

Step 2: plug in given x and k to find the missing y

y = 2.4 * 8

y = 19.2
