Answer:
The midpoint is at 20
Step-by-step explanation:
The midpoint of a segment
Given a segment in the number line with endpoints A(xa) and B(xb).
The midpoint coordinate is calculated as follows:
[tex]\displaystyle xm=\frac{xa+xb}{2}[/tex]
We are given the coordinates xa=10 and xb=30, thus the coordinate xm of the midpoint M is at:
[tex]\displaystyle xm=\frac{10+30}{2}[/tex]
[tex]\displaystyle xm=\frac{40}{2}[/tex]
xm = 20
The midpoint is at 20
