Half the sum of a number and 26 is 15. What is the number?(1 point) Responses -11 -11 4 4 5.5 5.5 -22

Let's call the number "x."

The expression "half the sum of a number and 26" can be represented as (1/2)(x + 26).

According to the problem, this expression is equal to 15, so we can form the equation:

(1/2)(x + 26) = 15

To solve for x, we can multiply both sides of the equation by 2 to remove the fraction:

x + 26 = 30

Subtracting 26 from both sides of the equation gives us:

x = 4

Therefore, the number is 4.
