Let come up with a value to represent 7th graders and 6th graders.
7th=x
6th=y
Y= 0.25x
X+y=135
Plug in 0.25x for Y
X+0.25x=135
X=108 7th graders
Y=27 6th graders
3n+5-6
Just simplify it, so now you have 3n-1
Let's go through each answer.
A) 3n+11 is incorrect because it does NOT equal 3n-1
B) 8n-6 is also incorrect because it does NOT equal 3n-1
C) 3n-1 IS correct because it DOES equal 3n-1
D) 3n+1 is incorrect because it does NOT equal 3n-1
So, your answer is C) 3n-1

Answer:
I don't really understand but Hope's this helps
Step-by-step explanation:
what is the question
1 * 10^6
comma is moved back 6 times
Y - y₁ = m(x - x₁)
y - 1 = -2(x - 3)
y - 1 = -2(x) + 2(3)
y - 1 = -2x + 6
+ 1 + 1
y = -2x + 7
The answer is A.
