To solve this problem, let's translate the given information into an equation.
Let's represent the number as "x."
The sum of the number and 10 is x + 10.
Half of this sum is (1/2)(x + 10).
According to the problem, this value is equal to 8.
Therefore, we have the equation:
(1/2)(x + 10) = 8
To solve for x, we can multiply both sides of the equation by 2 to eliminate the fraction:
x + 10 = 16
Next, subtract 10 from both sides of the equation to isolate x:
x = 16 - 10
x = 6
Therefore, the number is 6.
The correct answer is B) 6.
Half the sum of a number and 10 is 8 find the number.
