Direct Variation: y = kx. Plugging in 5 as y and 4 as x, we get 5 = 4k, k = 5/4.
Now we can find y: y = (5/4)(12) = 15, so y = 15.

Brian (I think you meant Brian haha..) is incorrect because the tenth place is the number right after the decimal which is a 4. If you are rounding to the tenth place that means that you have to look at the number to the right of that, which is 4. 5 and up means you round up and 4 and down means you round down. This is a 4, so you keep the 4 after the decimal and get rid of the last 4. Therefore, when rounded it would be: 4.4.
Hope this helped! Good luck! :)
A = 1/2bh
Divide h by both sides.
A/h = 1/2b
Divide 1/2 by both sides.
b = 2a/h
