Answer:
Explanation:
-4y - 3x = -11 (1)
x - 2y = 17 (2)
x = 17 + 2y
Substitute x value in (1)
-4y - 3(17 + 2y) = -11
-4y - 51 - 6y = -11
-10y - 51 = -11
-10y = -11 + 51
-10y = 40
y = 40/-10
y = -4
Substitute the y value in (2)
x - 2(-4) = 17
x + 8 = 17
x = 17 - 8
x = 9
Therefore, x = 9 and y = -4
Answer: I believe the answer is 800 students

I really Hope it helps
The answer would be B) 80
To find the answer you would use the equation x/250 = 32/100. Then, you would cross multiply (multiply diagonally). This would leave you with 100x=8000. Finally you divide by 100 on n=both sides of the equal sign, leaving you with x=80.
