By definition, we have to:
In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.
This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.
We have then, that the commutative property of the addition is:
3 + (-7) = (-7) + 3
Answer:
An expression that illustrates the commutative property of addition is:
3 + (-7) = (-7) + 3
you can conclude that lines A and B are parallel to each other
Ou paint 1/3 of a wall in 1/4 hour. At that rate, how long will it take you to paint one wall? rate = (area/time)
------
rate = (1/3)/(1/4) = 4/3 job/hr
-----
time for job = 3/4 hr/job = 45 minutes to do the whole job.
