Order the steps below in the correct sequence to prove that AC = 10. Reasons for
each step are shown in parentheses.
Given: Point B is on AC. AB = 3 and BC = 7
Prove: AC 10

? AC = AB + BC(Segment Addition Postulate)
? AC = 3 + 7 (Substitution)
? Point B is on segment AC. AB = 3 and BC = 7. (Given)
? AC = 10(Simplifying)
