Answer:
divide 8 miles by 3 hours to find how many miles he runs in 1 hour:
8 /3 = 2 2/3 miles in one hour.

3 / 2 2/3 = 1 1/8 hours (1 hour 7.5 minutes) to run 3 miles.
Answer:
6) x = 36°, y = 18°
7) z = 7°
Step-by-step explanation:
6) 2x + 3x = 180°
5x = 180°
x = 36°
4y = 2x = 72°
y = 18°
7) 2z + 4 = 4z - 10
2z = 14
z = 7
