3x + 8 = -x + 20 What is x?
g100num [7]
First, lets take all the x values on one side.

3x + x + 8 = -x + x + 20
4x + 8 = 20

Now, lets put the numbers on the other side.

4x + 8 - 8 = 20 - 8
4x = 12
x = 3

Hope this helps!

What is the mean? Round to<br> one decimal place.<br> 1,6,2,7,9
Viefleur [7K]

Answer:

5

Step-by-step explanation:

The mean represents an average of all the numbers, so we have \frac{sum-of-all-numbers}{total-amount-of-numbers}. Although that may seem confusing, it's actually pretty easy.

We have a total of five numbers, which are 1, 6, 2, 7, and 9.

We add these numbers up to find the sum, so 1 + 6 + 2 + 7 + 9 = 25

So our final answer will be \frac{25}{5} which can be simplified to 5.
