Answer:

Step-by-step explanation:

The problem is clearly addition, so we can rule out B and C. Associative property is the movement of the parentheses, whereas commutative property is the movement or reorganization of the numbers. The parentheses moved in this problem, so it is associative. I suggest reviewing these properites, they come in handy later and are good to know :)

Answer:

(d) ASSOCIATIVE PROPERTY OF ADDITION.

Step-by-step explanation:

"Associative Property Of Addition" means that in an addition expression; even if we make different groups with same given whole numbers, then also the sum in all the groups always remains the same. This property is also known as Associative property of Addition of Whole Numbers.

According to this question we were given:-

Group 1 = 3+(4+5) = 3+9 = 12

Group 2 = ( 3+4 ) +5 = 7+5 = 12

As, in both the groups the sum is same that is 12.

Therefore, whole numbers are associative under addition.

Hope this helps you!! (^_^)

Evalute the experssion -280+12x=

Alina [70]

The answer is 23 1/3. First, you need to add 280 to both sides of the equations in order cancel out 280 and get 12x by itself. But remember whatever you do to one side of an equation, you must to do the other. So now you have 12x=280. Now divide both sides of the equation by 12 in order to get x completely isolated. 280 divided by twelve is 23 1/3.
