Answer:
x = 30
Step-by-step explanation:
-6 + 24 = x - 24 + 24
x = 24 + 6 - 24 - 24
x = 30 - 0
x = 30
The sum of all the measurements is just the average times the number.
So if the average of all 92 is 7 the sum of those is
The average of the last two is 7.2 so their sum is
That means the sum of the first 90 is
so the average of the first 90 is
cm
