Answer:
20 mph.
Step-by-step explanation:
Unit rate = distance / time
= 80/4
= 20 miles per hour.
1
2x + 9 - 17x - 15 - x =????
2x - 17x - x + 9 - 15 = 0
- 15x - x - 16 = 0
- 16x - 16 =0
-16x = 16
x = 16 / - 16
x = 1
10,000,000,000,000,000,000,000,000,000,000,000,000,000,000
10,000,000,000,000,000,000 x 1,000,000,000,000,000,000,000,000 =
3x(2) + 2(2x - 20) = 16 - 2x(2)
6x + 4x - 40 = 16 - 4x
10x - 40 = 16 - 4x
14x - 40 = 16
14x = 56
x = 4
Hope this helps! ;)
