Question

find the midpoint, m, of ab.
a
m
b
20
?
54

Explanation:

Step1: Use the midpoint formula

The midpoint formula for two points \(x_1\) and \(x_2\) on a number line is \(M=\frac{x_1 + x_2}{2}\). Here \(x_1 = 20\) and \(x_2=54\).

Step2: Substitute the values into the formula

\(M=\frac{20 + 54}{2}\)

Step3: Calculate the sum in the numerator

\(20+54 = 74\), so \(M=\frac{74}{2}\)

Step4: Perform the division

\(\frac{74}{2}=37\)

Answer:

\(37\)
