2 times the sum of a number and 8 is equal to the difference of 10 and that number find the number

1 answer:

7 0

The equation would look like this
2 (x + 8) = 10 - x
First you distribute: 2x +16 = 10 - x
Next you isolate the variable by adding x to each side and subtracting 16 from each side: 3x = 10 - 16
Simplify: 3x = -6
Divide both sides by 3: x = -2

Answer:

A measure of average is a value that is typical for a set of figures. Finding the average helps you to draw conclusions from data. The main types are mean, median and mode. Data is also often grouped.

Step-by-step explanation:

To find the mean add all the ages together and divide by the total number of children.

If you type all those ages into a calculator it is easy to make an error.
