There would need to be 25 adult chaperones.
The ratio would be 3 adults to every 15 kids. 3:15
To find how many adults are needed for 125 kids you would simply divide.
125/5=25
Hope this helps! :)
Subtract the equations straight down. So we'll subtract the x terms together
5x - 5x = 0x = 0
meaning the x terms effectively go away after subtraction
Then we do the y terms together in the same exact order
y-3y = -2y
Then finally the right hand side values
6 - (-5) = 6+5 = 11
All of that work done indicates we have 0x-2y = 11 which is the same as -2y = 11. Divide both sides by -2 and we end up with y = -11/2
This answer isn't listed so I'm thinking there's a typo your teacher made somewhere.

g = 25 - 12 = 13
Equation of an ellipse

is given by:

As definition of an ellipse is that locus of all the points in a plane such that it's distance from two fixed points called focii remains constant.
Consider two points (a,0) and (-a,0) on Horizontal axis of an ellipse:
Distance from (a,0) to (c,0) is = a-c = 
Distance from (-a,0) to (c,0) is = a + c = 
a -c + a +c
= a + a
= 2 a →(Option A )
