20

Which statement could be used in step 2 when proving x = 30?
ORP and ORN are a linear pair
ORP and ORN are vertical angles
80 = 3x +10
x = 30

ORP and ORN are a linear pair

95

What is the missing statement and the missing reason in step 5?
Statement: 60 = 3x + 15; Reason: substitution
Statement: x = 15; Reason: subtraction property of equality
Statement: 60 = 3x + 15; Reason: transitive property
Statement: x = 15; Reason: subtraction and division properties of equality

Statement: 60 = 3x + 15; Reason: substitution
