Question

find the midpoint, m, of (overline{ef}).
e
m
f
6
18
(m=)
?

Explanation:

Step1: Use mid - point formula

The mid - point formula for two points \(x_1\) and \(x_2\) on a number line is \(M=\frac{x_1 + x_2}{2}\). Here \(x_1 = 6\) and \(x_2=18\).

Step2: Substitute values

Substitute \(x_1 = 6\) and \(x_2 = 18\) into the formula: \(M=\frac{6 + 18}{2}\).

Step3: Calculate

First, add in the numerator: \(6+18 = 24\). Then divide by \(2\): \(\frac{24}{2}=12\).

Answer:

$12$
