Question

find the midpoint, m, of $overline{ef}$. e 10 m f 20 m = ?

Explanation:

Step1: Recall mid - point formula

For two points \(a\) and \(b\) on a number line, the mid - point \(M=\frac{a + b}{2}\). Here \(a = 10\) and \(b=20\).

Step2: Substitute values

\(M=\frac{10 + 20}{2}\).

Step3: Calculate

\(M=\frac{30}{2}=15\).

Answer:

15
