You have $284 in your credit card balance. 186-174= 12. 99+35= 134 and then 12-134= -122. So 406-122= 284.
Answer:
I need this answer!!
Step-by-step explanation:
If x and y are complimentary.....x + y = 90
if x and z are supplementary....x + z = 180
and y + z = 190
x + y = 90.....x = 90 - y
x + z = 180
90 - y + z = 180
z = 180 - 90 + y
z = 90 + y
y + z = 190
y + 90 + y = 190
2y + 90 = 190
2y = 190 - 90
2y = 100
y = 100/2
y = 50 <===
x = 90 - y
x = 90 - 50
x = 40 <===
z = 90 + y
z = 90 + 50
z = 140 <===
z - x - y = 140 - 40 - 50 = 50 <==
