Answer:
B. the mean of city A is greater than the mean of city B
Step-by-step explanation:
Find mean by adding every number than dividing by the total of numbers added so...
97+98+96+98+99=488 and 488/5=97.6 which is higher than the mean of city B
4x + 6 = 9 is the equation
Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
