This means for every 5 students there will be 1 teacher so 550/5=110
So answer is 110 teachers

Step-by-step explanation:plug in for x.7(2y-4)+5y=6-6614y-28+5y=-6619y-28+-6619y=-38y=-2put it back in.
I believe it is 17.0, I hope this helps some
8+2x is the answer. The rest of these characters is for the >20 rule
Answer:
18, 19, 20, 21
Step-by-step explanation:
Just like any of these problems, we should start by forming an equation for us to get a reference and plug in. We'll be using x as our variables.
As we have four consecutive integers (and not multiples) we can assume that the integers will be x, x+1, x+2, and x+3.
The sum of the two largest integers we have equals: n+2 + n+3 = 2n+5
and three times the sum of the two smallest = 3(n + n+1) = 6n+3
and the sum of t he two largest subtracted from three times the sum of the two smallest = (6n+3) - (2n+5) = 4n-2
4n-2=70
4n=68
n = 18.
n = 18, n+1 = 19, n+2 = 20, n+3 = 21
