Mathematics

polet [3.4K]4 years ago
6 0

Equation:

8 - 3 * x = 2 → we solve for 3 * x

8 - 3x = 2 → we take 8 to the right side of the equation

-3x = 2 - 8 → we solve for 2 - 8

-3x = -6 → we take -3 to the right side of the equation

x = -6 / -3 → we solve for -6 / -3

x = 2 → final answer


Proof:

8 - 3 * 2 = 2 → we solve for 3 * 2

8 - 6 = 2 → we solve for 8 - 6

2 = 2 → numbers are the same, meaning our equation is correct


Answer:

\boxed{\bf~x~=~2}

The number of goals scored by a hockey team in each of its first 10 games is 2, 4, 0, 3,4, 1, 3, 1, 1, and 5. Find the mean numb
Artemon [7]
The mean is the average number from the group of numbers.
In this case, the average of the numbers 2, 4, 0, 3, 4, 1, 3, 1, 1, 5 is 2.4.
This is discovered by adding all the numbers together (which in this case is 24) and dividing that number by the amount of numbers in the group (in this case it's 10). 
24 ÷ 10 = 2.4
Therefore the mean is 2.4.
