Answer:
3*2 is 6 not 9 in 1st one in formula(x-3)
Start with the standard form of a circle, where 
is the center of the circle and 
is the radius.
Plug in the known values.
This is the circle's equation in standard form.
We suppose that every one paid $10 for entrance. So the total paid should be $1000. Now there is $300 more. The faculty should pay $15 more than student. So the faculty number is $300/15=20. Then the number of student is 80.
Answer:
w = 12
Step-by-step explanation:
2(4w-1)=-10(w-3)+4
2*4w + 2*-1 = (10*w + 10*-3) + 4
8w - 2 = 10w - 30 + 4
8w - 2 = 10w - 26
26 - 2 = 10w - 8w
24 = 2w
w = 24/2
w = 12
Check:
2((4*12)-1) = 10(12-3) + 4
2(48-1) = 10(9) + 4
2*47 = 90 + 4 = 94
