What? This isn’t a question
The answer is 3. 20/2=10 10-7=3
Fin how much was taken out
9 750 ml
9 times 750=6750ml
he has an 8 liter jug
1 liter=1000ml
convert 8L to ml
8 times 1000=8000ml
full-takenout=remaining
8000-6750=1250ml remaining
answer is D
also 5 kilometers
1 kilometer=1000 meters
5 times 1000=5000meters
answers are
D 1250 ml
5000meters jogged
We effectively rewrite the equation as
In order for the LHS to be defined, we need to restrict 
, or 
. Now, the LHS will vanish when the numerator is 0, which happens for
This value is indeed smaller than 4, so the solution is 
.
