Alright First you combine the like terms.
9n - 3n = 6n
21 - 24 = -3
Rewrite the simplified equation
6n - 3 = 0
Solve for n
6n = 3
n = 3/6
n = 1/2

D. If you ask the amount of projects completed using the computer lab you are asking a statistical question. Hope this helps!
Answer: The answer is F.
Step-by-step explanation:
1.) The first equation represents how the spiral notebook has 30 more pages than the the memo book, and how subtracting the memo book's pages would result with 30.

Answer:
option (A) 62 miles
Step-by-step explanation:
Data provided in the question:
Ratio on the left = 434 miles : 14 gallons
ratio on the right = ?? : 2 gallons
Now,
The ratio on the both sides are equal
let the unknown value in the ratio be 'x'
Now, the ratio a : b can also be represented as 
therefore,
434 miles : 14 gallons = x : 2 gallons
or
⇒ 
= 
or
⇒ x = 
or
⇒ x = 62 miles
Hence,
the correct answer is option (A) 62 miles
