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
A) 3000 * 0.5 = 1500 minutes, or 25 hours.
b) 10,000 * 0.5 = 5000 minutes, or 83 hours and 20 minutes
c) she works 2 hours a weekday. 2 hours = 120 minutes. It takes her 83 hours and 20 minutes to finish a 10,000 piece puzzle. It will take her 42 weekdays to finish this. Jan 15, 2020 is a Wednesday. She will finish it on March 12, 2020.

Answer:
456,976,000
Step-by-step explanation:
The total number of possibilities is the product of the number of possibilities in each of the character positions:
10 · 10 · 10 · 26 · 26 · 26 · 26
= 10^3 · 26^4 = 456,976,000
