10 yellow cards over 30 = 10/30
second selection : 9 yellow cards over 29 = 9/29
10/30 * 9/29 = 1/3 * 9 /29 = 3/29 = 0.1034 = 10.34%

Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104
The measure of angles are 76 and 104
Say you're making a recipe that needs 2 1/2 cups of water. But you want to make two servings, so you need to know what 2 1/2 + 2 1/2 equals. Or maybe you need a half cup of milk but you don't have enough. You need to know how much left you need so you can buy or borrow the right amount.
1) 63-13=s
2) 73-7=?
4) 80-17=?
6) ?-18=74
That's all I know :)
