Question

line segment ab measures 18 units. what is the distance between tick marks on the number line? 1 unit 2 units 3 units 9 units

Explanation:

Step1: Count tick - mark intervals

Count the number of intervals between A and B. There are 6 intervals between A and B.

Step2: Calculate distance per interval

Divide the length of AB by the number of intervals. Let \(d\) be the distance between tick - marks. Given \(AB = 18\) units and number of intervals \(n=6\), then \(d=\frac{18}{6}\).

Answer:

C. 3 units
