The answer is D or the fourth choice, 12
Answer: 48
Step-by-step explanation:
Here's the complete question:
The mean number of people per household in eight households is six people. what is the total number of people in the eight households?
First and foremost,we should note that mean means the average of a given set of numbers.
Since the mean number of people per household in eight households is six people, the total number of people in the eight households would be calculated by multiplying 6 by 8. This would be:
= 6 × 8
= 48 people
Answer:
because x is the middle integer of three consecutive integers
=> The remaining 2 numbers respectively are x - 1 and x + 1
=> the sum of these three integers is
x - 1 + x + x + 1 = 3x
8-4x-7=5x+30-2
combine like terms
1-4x=5x+28
-27=9x
divide both sides by nine
-3=x
