Which mathematical property is demonstrated? if w = –8 and –8 = u, then w = u. a. symmetric property of equality b. transitive property of equality c. closure property of addition d. closure property of multiplication

Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
