8x+3y=7
3x+5y= -9
900/45 = 20
so ratio of middle school students and teachers: 900:45 = 20:1
if high school student-teacher ratio as middle school then
x/110 = 20/1
so x = 110 * 20 = 2200
answer is C) 2200
Answer:
16 friends
Step-by-step explanation:
If the question you're asking is how many friends he gave chocolates to, the answer would be 16.

Applying division signal rules, from the graphs of both functions, it is found that the solution of the inequality is:
------------------
A fraction, which represents a division, is negative if the numerator and the denominator have different signals. Thus, to solve this inequality, we have to study the signals of the numerator and the denominator.
The numerator is:
The denominator is:
Thus, the solution is:

Answer:
x ∈ [-3;-1) ∪ [2;4)
Step-by-step explanation:
we have this board:
x -3 -1 2 4
x - 2 - - - 0 + +
x+3 - 0 + + + +
x+1 - - 0 + + +
x-4 - - - - 0 +
+ 0 - || + 0 - || +
from the board
=> x ∈ [-3;-1) ∪ [2;4)
