Either order is correct.
Small example: let's take
. Then
By the commutative property, we can write
By the associative property, we can regroup consecutive terms.
By the associative property again, we can regroup terms and write
Commutativity:
Associativity:
You can show by induction that this holds in general for
so that
.
50. It's 0.25 x 200. Or 1/4 of 200
Answer:The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm). Highly trained athletes may have a resting heart rate below 60 bpm, sometimes reaching 40 bpm. The resting heart rate can vary within this normal range.

No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
