To find the value of y when x = 24, you can set up a proportion using the given information.
Since the value of y varies directly with x, you can set up the proportion as:
y1/x1 = y2/x2
Plugging in the values we have:
12.8/16 = y/24
Cross multiplying gives:
12.8*24 = 16*y
307.2 = 16y
Divide both sides by 16 to solve for y:
y = 19.2
Therefore, the value of y when x = 24 is 19.2.
The value of y varies directly with x. When x=16, y=12.8. What is the value of y when x=24?
