Question

find the midpoint, m, of $overline{st}$. s 3 m t 15 m = ?

Explanation:

Step1: Recall mid - point formula

The mid - point of two numbers \(a\) and \(b\) is \(\frac{a + b}{2}\).

Step2: Identify \(a\) and \(b\)

Here \(a = 3\) and \(b=15\).

Step3: Calculate the mid - point

\(\frac{3 + 15}{2}=\frac{18}{2}=9\).

Answer:

9
