Search diligently through the exercises in the first few chapters of an Elementary
Algebra textbook. You're bound to get lucky within the first two or three books.
All percentage problems can be solved like this: "of" means "times" "is" means "equals" n * 54 = 45 Take 45 and divide it by 54 and change the result to a percent (multiply by 100.)
If there were n questions, then 100*45/n or 4500/n per cent.

n x 125/100 = 600 n = 600 x 100/125 = 480
300
n equals 52
It is 84456000.
-45
N represents 100
You cannot, unless n is a counter in a program or algorithm for a looping process. In that case, you need to know what the algorithm is doing.
If 45 + n = 29, then n MUST equal -16
1/100 or 0.01
350n=35000 n=35000/350 n=100
False. f(n) = n/45 describes how long (in hours) it takes to travel n miles at 45 mph since time = distance ÷ speed. Whereas distance = speed x time which would be f(n) equals n times 45.
All percentage problems can be solved like this: "of" means "times" "is" means "equals" n * 54 = 45 Take 45 and divide it by 54 and change the result to a percent (multiply by 100.)
N = 0.007.
shut the hell up that is the answer
