Answer:
495 students are at Lincoln Middle School
Step-by-step explanation:
450/?
450 = 90%
450*90% = 450 * 0.90 = 405
450- 405 = 45
450+45 = 495
Sector Area = (central angle / 360) * PI * radius^2
Sector Area = 300 / 360 * PI * 8^2
Sector Area = (5/6) * 64 * PI
Sector Area = 53.3 * PI

18/35 is halfway between 3/5 and 5/7. Do you want me to explain or just the answer?
Answer:
(1, -1/2)
Step-by-step explanation:
7x - 2y = 8
5x + 2y = 4
I would use elimination to get rid of y
Add the two equations together
7x - 2y = 8
5x + 2y = 4
-------------------------
12x = 12
Divide each side by 12
x =1
Now find y
5x+2y = 4
5*1 +2y =4
Subtract 5 from each side
5+2y -5 = 4-5
2y = -1
Divide by 2
2y/2 =-1/2
y = -1/2
