She can not fit more than twenty rows in the class so anything equal to twenty or less (not including zero or negative numbers) would be fine. We don't have a limit for how many chairs in a row so I'm answering assuming that is not a problem so 20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2, or 1 row(s) would be possible

Answer:
$0.50
Step-by-step explanation:
Each trip transports 50 packs at 12 kg each, for a total of 600 kg. That trip nets $300 in income.
Lennox gets paid ($300)/(600 kg) = $0.50/kg, or 50¢ for 1 kg of apples
Replace all the variables that we know the value for.
-3 = |x|
Make to equations from this one.
-3 = x and -3 = -(x)
Solve the first one.
-3 = x
x = -3 <-- Switch it around
-3 = -(x)
-(x) = -3 <-- Switch it around
x = 3 <-- Divide both sides by -1
So, there are two possible answers, -3 and 3.
