Each expression with the appropiate property:

It is the Commutative property.

Step-by-step explanation:  The word commutative comes from the word "move around" in this case all the numbers did was switch positions. Another example;  2+3=3+2  that is commutative property because the numbers were moved. Much similar to your problem

step-by-step explanation:

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
