Additive Inverse And Distance Between Two Points On A Number Line
Standard(s): 7.NS.A.1.C
Kyle and Mark started at the same location. Kyle traveled 5 miles due east, while Mark traveled 3 miles due West. How far apart are they?
A
2 miles
B
8 miles
C
15 miles
D
12 miles
Standard: 7.NS.A.1.C
Domain: The Number System
Theme: Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers.
Description: Understand subtraction of rational numbers as adding the additive inverse, p ? q = p + (?q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
Which of the following is the same as 7 – (3 + 4)?
A
7 + (–3) + (–4)
B
7 +(–3 + 4)
C
7 + 7
D
–7 – 7

Which of the following expressions represents the distance between the two points?
A
|4-3|
B
(-3)-4
C
|(-3)-4|
D
4-3
