Answer:
300
Step-by-step explanation:
400 - 35 - 65 = 300
100 seats being used, so 300 seats left unused
(Btw, do you happen to know of a certain Northeast Middle School at all?)
Answer:The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point. On the graph, that would mean a change of x values.

Step-by-step explanation:
Your question is poorly formatted. However, I'm able to deduce that your question involves at least 2 algebraic fractions that needs to be simplified.
So, I'll make use of the following expression:
![\frac{3n}{n + 3} + \frac{5}{n - 4}](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7Bn%20%2B%203%7D%20%2B%20%5Cfrac%7B5%7D%7Bn%20-%204%7D)
When you follow the steps I'm about to provide, you'll arrive at the right answer
Required
Determine an equivalent expression
![\frac{3n}{n + 3} + \frac{5}{n - 4}](https://tex.z-dn.net/?f=%5Cfrac%7B3n%7D%7Bn%20%2B%203%7D%20%2B%20%5Cfrac%7B5%7D%7Bn%20-%204%7D)
Step 1: Take L.C.M of the denominators
![LCM = (n+3)(n-4)](https://tex.z-dn.net/?f=LCM%20%3D%20%28n%2B3%29%28n-4%29)
Step 2: Evaluate the fractions
![= \frac{3n(n-4)+5(n+3)}{(n+3)(n-4)}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3n%28n-4%29%2B5%28n%2B3%29%7D%7B%28n%2B3%29%28n-4%29%7D)
Step 3: Open the brackets at the numerator
![= \frac{3n^2-12n+5n+15}{(n+3)(n-4)}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3n%5E2-12n%2B5n%2B15%7D%7B%28n%2B3%29%28n-4%29%7D)
Step 4: Collect and evaluate like terms
![= \frac{3n^2-7n+15}{(n+3)(n-4)}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B3n%5E2-7n%2B15%7D%7B%28n%2B3%29%28n-4%29%7D)

Answer:
You don't need to gather several points of data to answer the question. For example, the question, 'What is 2 plus 2?' is a non-statistical question. This question has only one correct answer that doesn't change.
