Answer:
7/18
Step-by-step explanation:
-4 × -7
9 × 8
28/72, which would simplify to 7/18
2:20
60 minutes subtracted from 4 p.m. is 3 p.m. Since it was 100 minutes, there are 40 minutes to take away from 3 p.m.
The term "supplementary" means that the two angles add up to 180°, which means we can write an equation:
17x + x = 180
18x = 180
÷ 18
x = 10
And now you can multiply 10 by 17, because it is 17 times the angle, to get 170° and 10° as your answer.
I hope this helps!
