Question

Suppose y varies directly with x, and y = 24 when x = 8. What is the value of y when x = 10?
10
30
80
240

Answer 1

use y= kx

here they give you y=24 when x=8, so you can use these numbers in
y=kx and "solve" for k

then replace k with that number in
y= kx
finally, replace x with 10 to find the y

Answer 2

-.- just think if y=24 when x=8 that means that 3x=y
so if x=10 that would mean y=30

Answer 3

:D

Answer 4

look at the question im posting now? its still math.

Answer 5

ok :)
