7(12 1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8
12 1/3 = 12.33
1/4 = 0.25
7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 = 3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94
False. The x, when 12 1/3 does not work inside this equation

Answer:
The mean is 6.2.
Step-by-step explanation:
The "mean" is the same thing as the "average". Essentially, the question is asking for the average of the numbers.
So:
Add up all of the terms. [6 + 11 + 5 + 2 + 7] = 31
You find the average by dividing the sum of the terms (31) by the number of terms (5).
31/5 = 6.2
The mean is 6.2.

Answer:
26 wins , 14 ties
Step-by-step explanation:
Given: Hockey teams receive
points when they win and
point when they tie. One season, a team won a championship with

To Find: How many wins and how many ties did the team have.
Solution:
let the number of wins hockey team have 
let the number of ties hockey team have 
Now,
Hockey teams receive
points when they win and
point when they tie.

They won
more games than they tied

Solving both equations we get


Hence, the hockey team have
wins and
ties.
