3 N8.1.c: Which equation best represents the distance
between –19 and 5.5 on the number line below?
15.5+ (-19)1 = 13.5
15.5 - 19= 13.5
15.5 - (-19)1 = 24.5
-19 - 5.5 = –24.5

Answer 1

19 - 5.5 = 13.5 is the equation that best represents the distance between -19 and 5.5 in the number line.

Explanation:

• Let us consider that the integers -19 and 5.5 are placed in the number line.
• To find the distance between these two integers in the number line, a simple method is followed.
• That can be done by taking the absolute value of the difference of those numbers.

Therefore, the absolute value of |-19| is 19.

And the absolute value of |5.5| is 5.5

Now, find the difference between the absolute value of those two numbers -19 and 5.5

⇒ |-19| - |5.5|

⇒ 19 - 5.5

⇒ 13.5

Now look for the options in which the equation shows 19 - 5.5 = 13.5

Thus, the equation that best represents the distance between -19 and 5.5 is 19 - 5.5 = 13.5
