Answer:
x = 8
Step-by-step explanation:
Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.
16x-4 + 7x = 180, combine like terms
23x - 4 = 180, add 4 on both sides (isolate variable)
23x = 184, divide 23 on both sides
x = 8
Answer:
173.83
Step-by-step explanation:
17.4 * 9.99
173.826 ~ 173.83
the additive inverse of -8 is 8
to find the additive inverse you just have to change the sign of the number


No, since 0 doesn't belong to the domain.
