Let's call the number we are trying to find x. The problem states that half the sum of the number and 10 is 8, so we can write the equation:
(1/2)(x + 10) = 8
To solve for x, we can multiply both sides of the equation by 2 to get rid of the fraction:
x + 10 = 16
Next, subtract 10 from both sides of the equation:
x = 6
Therefore, the number is 6.
Half the sum of a number and 10 is 8. Find the number.
