keeping in mind that a year has 12 months, thus 6 months is really 6/12 of a year.
Answer:
n + 4
Step-by-step explanation:
It´s like a normal sum, but since the number is unknown just put n.
10. 150
11. 1250
12. 105
13. 158000
15. B
10% is $8.00 so 20% is $16 and 80-16= 64 so the sale cost is $64.00
supplementary angles add up to 180 degrees
x + y = 180
x - y = 92
---------------add
2x = 272
x = 272/2
x = 136 <=== this is one angle
x + y = 180
136 + y = 180
y = 180 - 136
y = 44 <=== this is ur other angle
