Question

what is the coordinate of the midpoint of $overline{tu}$? write your answer as an integer or a decimal, or mixed number in simplest form.

Explanation:

Step1: Identify the coordinates of T and U

Let the coordinate of T be $x_1 = 885$ and the coordinate of U be $x_2=887$.

Step2: Use the mid - point formula

The mid - point formula for two points on a number line is $\frac{x_1 + x_2}{2}$. So, $\frac{885+887}{2}$.

Step3: Calculate the sum in the numerator

$885 + 887=1772$.

Step4: Divide by 2

$\frac{1772}{2}=886$.

Answer:

886
