Best ResponseYou've already chosen the best response.0The answer would be commutative because it changes order.

Best ResponseYou've already chosen the best response.1so is the answer for this on B Which is an example of the commutative property? A. –13 + 27 = 27 + (–13) B. –21 + (11 + 13) = (–21 + 11) + 13 C. 4(–3 + 5) = 4(–3) + 4 ∙ 5 D. –(–8 + 3) = 8 + (–3)

Best ResponseYou've already chosen the best response.1Commutative property is a change of order. Here is the general way of stating the commutative property of addition: a + b = b + a

Best ResponseYou've already chosen the best response.0I am talking about the second problem

Best ResponseYou've already chosen the best response.1For the second problem, in B., the 11 and 13 were grouped together on the left side. On the right side, the 21 and 11 are grouped together. This is a change of grouping, so B is associative, not commutative.

Best ResponseYou've already chosen the best response.1You need to find a statement that is an example of a + b = b + a, which is commutative.

Best ResponseYou've already chosen the best response.1It is not "communicative." Communicative means you like to communicate. It is "commutative." Commutative means you change, as in change the order.

Best ResponseYou've already chosen the best response.1Commutative: See if one of the choices shows this: (first number) + (second number) = (second number) + (first number)

Best ResponseYou've already chosen the best response.1Commutative property of addition. (first number) + (second number) = (second number) + (first number) a + b = b + a Example: 3 + 5 = 5 + 3

Best ResponseYou've already chosen the best response.1i now it has 2 be 3 but im not sure if it is 3 or 3

Best ResponseYou've already chosen the best response.1Let's use the distributive property first on the left side. –(q + 14) = –3 + (–14) q + (14) = 3 + (14)

mathstudent55

Best ResponseYou've already chosen the best response.1Now you see that q must equal 3 That means q = 3, not 3

Best ResponseYou've already chosen the best response.1You are correct. q = 3

Best ResponseYou've already chosen the best response.1ok last thing Use an addition property to solve for b. –12 + 16 = 16 + b A. –28 B. –12 C. 4 D. 12

Best ResponseYou've already chosen the best response.1You want b alone on the right side. Since 16 is being added to b, you need to add something to 16 to make it zero. Additive inverses add to zero.

Best ResponseYou've already chosen the best response.1If you add 16 to 16 you get zero because 16 is the additive inverse of 16. The rule with an equation is you must add the same to both sides of the equation. Since you need to add 16 to the right side, you must add 16 to the left side too.
