Question

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

Explanation:

Step1: Count the number of intervals

There are 9 intervals between A and B.

Step2: Calculate the distance per - interval

Since the length of AB is 18 units and there are 9 intervals, we use the formula $d=\frac{AB}{9}$. Substituting $AB = 18$ into the formula, we get $d=\frac{18}{9}$.

Step3: Simplify the result

$\frac{18}{9}=2$.

Answer:

2 units
