what is the distance between 5 and -15 on a number line? units
Answer
Explanation:
Step1: Use the distance formula
The distance between two numbers (a) and (b) on a number line is (|a - b|). Here (a = 5) and (b=-15), so the distance is (|5-(-15)|).
Step2: Simplify the expression
(5-(-15)=5 + 15) (since subtracting a negative is adding the positive). Then (5+15 = 20). And (|20|=20).
Answer:
(20)
