<span>Use the order of operation, PEMDAS.
6²÷2(3) +4
36/2(3)+4
=(18)(3)+4
=54+4
=58</span>
7-3/-3-3
4/-6
this can be simplified to -2/3
(3) = -2/3(3) + b
Solve this
3 = -2 + b
5 = b
The answer is
y = -2/3x + 5
Answer:
45.29 miles per hour
Step-by-step explanation:
Speed is the distance over time. To find the average rate of speed for a trip, we simply need to take the total distance divided by the total time.
Avg. Speed = (188 miles + 197 miles) / (4 hours + 4.5 hours)
Avg. Speed = 45.29 miles per hour
Hence the average rate of speed for the trip was 45.29 miles per hour.
Cheers.

I'm fairly certain the answer is 1/3.
