The ratio of y to x is 6:2. If you multiply either one of them, you must do the same to the remaining number. So, when you multiply 6 by 2 to get 12, you must also multiply 2 by 2 to keep the ratio equal and the same. 2x2 = 4, so x=4 when y=12. Hope this helped! Good luck with other math problems :)
(180 - 5x + 12) + x + 3x + 8 = 180 180 - x + 20 = 180 -180 -x + 20 = 0 - 20 -x = -20 x = 20 Sorry for the confusion! I believe this is the correct answer
