Question

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

Explanation:

Step1: Identify the coordinates of D and E

The coordinate of D is 64 and the coordinate of E is 66.

Step2: Use the mid - point formula

The mid - point formula for a one - dimensional number line is $\frac{x_1 + x_2}{2}$, where $x_1$ and $x_2$ are the coordinates of the two points. Here $x_1=64$ and $x_2 = 66$. So, $\frac{64 + 66}{2}$.

Step3: Calculate the mid - point

$\frac{64+66}{2}=\frac{130}{2}=65$

Answer:

65
