Half the sum of a number and 10 is eight find the number

Question

Three
Six
Two
-2

Answer 1

To solve this problem, let's set up an equation:

Let's assume the number is "x".

Half the sum of a number and 10 is eight can be written as:

(x + 10) / 2 = 8

To find the value of x, we can multiply both sides of the equation by 2 to eliminate the fraction:

x + 10 = 16

Then, we subtract 10 from both sides:

x = 6

Therefore, the number is 6.
