Which shows the best use of the associative and commutative properties to
make simplifying 3/4– 5+ 9 - 2/4 + 2 easier?

O A. (+()] + [9+2+(-5)]
O B. (+9+(-5)] + [2+(-3)]
O c. (+(-5)] + [9+(-x) + 2]
O D. (2++(-5)] + [(-k) +9]

Answer :

littlewip999

Answer:

c

Step-by-step explanation:

The best use of the associative and commutative properties to

make simplifying 3/4– 5+ 9 - 2/4 + 2 easier is option C (+(-5)] + [9+(-x) + 2].

What is commutative property of addition?

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have:

x + y = y + x

Suppose you've got 3 numbers as a, b, and c.

Then, we have

(a+b) + c = a + (b + c)

This property is called associative property.

Given;

3/4– 5+ 9 - 2/4 + 2

We can simpliyfying it by using the properties of addition ;

3/4– 5+ 9 - 2/4 + 2

(-5) + 9 + 2 + 3/4 + (-2/4)

Hence, the best use of the associative and commutative properties to

make simplifying 3/4– 5+ 9 - 2/4 + 2 easier is option C (+(-5)] + [9+(-x) + 2].
