Associative property of addition

Step-by-step explanation:

We are given the statement and we are to determine whether which of the given answer options allows it to be written as .

According to the associative property of addition, you can add the numbers regardless of how they are grouped.

Therefore, (a + b) + c = c + (a + b) is possible with associative property of addition.

The answer is commutative - addition!

The reason it is not associative is because while the direction changes, the parentheses does not move! In the associative, the parenthesis moves, but in (a + b) + c = c + (a + b), the parenthesis contains a + b in both of them. Also here is some picture proof. (Attached)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
