Answer:
#8 - 52°, #9 - 29°
Step-by-step explanation:
8. The two angles added together are a straight line, so they sum up to 180 degrees.
x + (2x + 24°) = 3x + 24° = 180°
3x + 24° = 180°
3x = 156°
x = 52°
9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).
So, 4x + (2x + 6°) = 180°
6x + 6° = 180°
6x = 174°
x = 29°
Hope this helps. Get some rest. Zzzzz :)

Answer:
There are 200 middle school students
Step-by-step explanation:
The equation for this question can be: 40 is 20% of what. This can be simplified to 40 = 0.2x and then to get x by itself you divide 40 by 0.2 which is 200.
