Answer:
(-1,1)
Step-by-step explanation:
As seen in the picture, the only point the 2 lines connect are at (-1,1)
There are 83 full price and 140 half-price admissions.
There are 83 full price and 140 half-price admissions.
Two equations needed : x + y = 223 and 5x + 2.5y = 765
Use the first equation, x + y = 223 and rearrange it to fit the problem and substitute : y = 223 - x
5x + 2.5(223 - x) = 765
5x + 557.5 - 2.5x = 765
2.5x + 557.5 = 765
2.5x = 765 - 557.5
2.5x = 207.5
2.5x ÷ 2.4 = 207.5 ÷ 2.5
x = 83
_______________________
Now just subtract 223 and 83 to get the others:
223 - 83 = 140
All you have to do is subtract.
7 3/8 - 3 10/12
Change it into a common denominator: 24
7 3/8 = 7 9/24
3 10/12 = 3 20/24
7 9/24 - 3 20/24 =
6 33/24 - 3 20/24 = 3 13/24
Answer = 3 13/24 ( 85/24 )

12 a^2 + 60 a - 8
- (16 a^2 - 32 a + 9)
= -4 a^2 + 92 a - 17
Answer:
12
Step-by-step explanation:
|∛(-3·9) -9| = |-3-9| = |-12| = 12
