Hey there!
Since it's 30n, 30 is the coefficient and it's being multiplied by n.
We plug in n.
30(2) =
60
Hope this helps!

Step-by-step explanation:
Answer:
n = 9
Step-by-step explanation:
Step 1: Write equation
-4(9n + 9) = -12(4n - 6)
Step 2: Solve for <em>n</em>
<u>Distribute:</u> -36n - 36 = -48n + 72
<u>Add 48n to both sides:</u> 12n - 36 = 72
<u>Add 36 to both sides:</u> 12n = 108
<u>Divide both sides by 12:</u> n = 9
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
-4(9(9) + 9) = -12(4(9) - 6)
-4(81 + 9) = -12(36 - 6)
-4(90) = -12(30)
-360 = -360
Answer:
The correct answer to the following question will be "60 students".
Step-by-step explanation:
Marta will be taking a sampling frame from some kind of 600 student group.
Mean,
N = 60
Although the sampling method could perhaps consist of the following components 10% of the population,
⇒ 
⇒ 
In order to view these findings as autonomous, 60 students would then have to analyze Marta lacking replacements.
