Which algebraic properties was applied to the expression a + (b + c) = (a + b) + c?

andrew11 [14]

Answer:

the Associative Property

Step-by-step explanation:

Notice that the ORDER doesn't change -- a, b, c on both sides. But the GROUPING changes.

Example:

3 + (4 + 5) = (3 + 4) + 5

3 + 9 = 7 + 5

12 = 12

Subtraction does NOT behave this way!

8 - (7 - 1) = 8 - 6 = 2

(8 - 7) - 1 = 1 - 1 = 0

It matters who you associate with! :-)

ozzi

Answer:

Yes, they are correct. Hernando divided 6 by 6.

Step-by-step explanation:

Given that:

Hernando ate 2/8 of a pizza for dinner.

Let the pizza be x. Then:

Hernando ate $\dfrac{2}{8} \ \ o f \ \ x$

Then he gave the rest of the pizza to his friends

Hernando now carried out the following calculations to support his activities;

$\dfrac{6}{8} \div 6= \dfrac{6 \div 6}{8}= \dfrac{1}{8}$

$\dfrac{6}{8} \times \dfrac{1}{6}= \dfrac{6 \div 6}{8}= \dfrac{1}{8}$

From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get $\dfrac{1}{8}$ .

Thus, the correct answer is:

Yes, they are correct. Hernando divided 6 by 6.
