x = 8

Question

A Transitive Property
B Multiplication Property
C Addition Property
D Simplify
E Angle Addition Postulate
F Substitution
GSubtraction Property
H Divison Property
I Segment Addition Postulate

Answer 1

A Transitive Property: x = y, y = z, then x = z
B Multiplication Property: If x = y, then ax = ay
C Addition Property: If x = y, then x + a = y + a
D Simplify: simplify the expression or equation
E Angle Addition Postulate: If point D is in the interior of angle ABC, then angle ABD + angle DBC = angle ABC
F Substitution: replacing a variable with a specific value or expression
G Subtraction Property: If x = y, then x - a = y - a
H Division Property: If x = y, then x/a = y/a
I Segment Addition Postulate: If B is between A and C, then AB + BC = AC
