Answer:

Hi! For the first question, the property being demonstrated is the Commutative Property of Addition. For the second problem, the answer would be the Additive Identity Property of 0.

Step-by-step explanation:

In the problem 1.5 + 1.7 + 3.5 = 1.5 + 3.5 + 1.7, we can see the commutative property being used. The Commutative Property of Addition states that changing the order of the addends will not have an affect on the sum. As long as you still keep the same addends, the sum will always remain the same regardless of the order.

In the problem 16 + 0 = 16, we see the Additive property of 0 being demonstrated. This property basically states that adding a number to 0 will give you the same number. It is usually very easy to identify if you look for 0 being added to an addend.

Answer:

The correct answer is Adam rowed faster in the men's 500-meter kayak race.

Step-by-step explanation:

To find the speed he rowed in both races, you need to divide the distance of the race by the time it took him to finish. In the first race, he rowed 500 meters and did it in a time of 1 minute 37.9 seconds, so the speed in that race would be $\frac{500}{97.9}$ or approximately 5.10725 meters per second. In the second race, Adam rowed a distance of 1000 meters and did it in a time of 3 minutes 28.2 seconds, which means his speed in that race would be $\frac{1000}{208.2}$ or approximately 4.80307 meters per second. Since his speed in the first race was faster than his speed in the second race, Adam rowed faster in the first race would be the correct answer.
