Hey!

Steps To Solve:
-27 + m = 3m + 9
~Subtract m to both sides
-27 + m - m = 3m + 9 - m
~Simplify
-27 = 2m + 9
~Subtract 9 to both sides
-27 - 9 = 2m + 9 - 9
~Simplify
-36 = 2m
~Divide 2 to both sides
-36/2 = 2m/2
~Simplify
-18 = m
------------------------------------------------
Answer:
m = -18

Hope This Helped! Good Luck!
Answer:
3 hours
Step-by-step explanation:
Since the speed is remaining the same, time is proportional to distance, so you have ...
1.75 hours/(70 miles) = (additional hours)/(120 miles)
Multiply by 120 to find the additional hours:
additional hours = (120/70)·(1.75 hours) = 3 hours
_____
Units of miles cancel from numerator and denominator of (120 miles)/(70 miles).
According to the desired test, the hypothesis are given by:
D) H0: μ=210
Ha: μ ≠ 210
At the null hypothesis, it is <u>tested if the population mean is of 210 lbs</u>, that is:
At the alternative hypothesis, it is <u>tested if the population mean differs from 210 lbs</u>, that is:
Hence, the correct option is:
D) H0: μ=210
Ha: μ ≠ 210
