Answer:
The answer is stratified.
Step-by-step explanation:
Answer:
infinite solutions
Step-by-step explanation:
Multiply the first equation by 2
2(3x-5y) = 2*15
6x - 10y = 30
This is the same as the second equation
They are the same line
This means there are infinite solutions
This means for every 5 students there will be 1 teacher so 550/5=110
So answer is 110 teachers
