48, multiply -1 by -4 then multiply 4 by 12
PEMDAS
Answer:
20 meters
Step-by-step explanation:
The track is circular so it means that after Patrick raced the entire track he is back at the starting point. In other words, every 440 meters he is back to the beginning.
So we would have that, if he races round the track twice, he would run 440(2) = 880 meters and he would be back at the starting point.
The problem asks us how far is he from the starting point at the 900 meter mark. If at 880 meters he is at the starting point, then at 900 meters he would be
meters from the starting point.
441 is odd, so we can't divide it by 2.
Since the sum of its digits is
, which is divisible by 3, we can divide 441 by 3, and we have

Which is still divisible by 3, because
. We have

49 is not divisible by 3 anymore, nor by 5 (it doesn't end with 0 or 5).
It is divisible by 7 though, we have

and finally,

So, the factorization of 441 is

Answer:
3people/minute
Step-by-step explanation:
75/25=3
The answer is 20.
5*10-5*6=50-30=20
