Answer:
The wheels have to rotate 500 times
Step-by-step explanation:
The wheel is 1 meter in diameter so we need to find the circumference.
C = 2r
C = 21
C= 2
2meters = .002kilometers
1000meters = 1kilometer
1000/2 = 500

Answer:
6
Step-by-step explanation:
- 6x +5 = 0
- 6x + 9 -9 +5 = 0
[ - 6x + 9] - 4 =0
-4 = 0
= 4
(x-3) = or (x-3) = -
(x-3) = 2 or (x-3) = -2
x = 5 or x = 1
therefore, sum of these solutions is 5+1 = 6
