The first question is.
6 + 6 = 12
n is the same thing on both sides of the equation
6 + 6 - n = 12 - n
You are taking an equal amount off both sides so the left and right sides are both equal still. Try it. Let n = 0.5
6 + 6 - 0.5 = 12 - 0.5
6 + 5.5 = 11.5
11.5 =? 11.5
They are both equal. In algebra a letter in an equation like this one can't change values if that letter is on opposite sides of the equation.

9.5 y + 600 < 900
9.5 y = 300
y < 300 / 9.5
y < 31.57
If there's no sales tax where he lives, he can take 31 students. If it is possible to take 0.57 of a student then he can take 32 (but of course it isn't possible).

Answer:
h>5
Step-by-step explanation:
7 > 17 -2h
7 -17 > -2h ( -17 on both sides)
-10 > -2h ( simplify)
10 < 2h ( divide by -1 throughout)
2h > 10
h > 5 ( ÷2 throughout)
Since h is greater than 5, draw a small circle above the number 5 and draw the arrow towards the right. Do not colour the circle.
When an inequality is divided by a negative number, the sign changes.
