$\rule[225]{225}{2}$

Step-by-step explanation:

7.

The Commutative Property of Addition changes the order of the numbers but does not affect the sum.

8.

We will convert the values into decimals for simplicity.

$\sqrt{7} \approx 2.65$

$\sqrt{3} \approx 1.73$

$\displaystyle \frac{-1}{3} \approx -0.33$

Arranging from least to greatest:

$\displaystyle -2.3, \ \frac{-1}{3} , \ \sqrt{3} , \ \sqrt{7} , \ 5.1$

9.

2 + ( -8 )

2 is on the number line.

When -8 is added to 2, the value decreases, and it moves 8 units to the left side.

The result is -6.

10.

The two subsets of real numbers are rational and irrational numbers.

$\sqrt{13}$ is an irrational number.

11.

$\displaystyle \frac{12x-8}{4}$

$\displaystyle \frac{12x}{4}-\frac{8}{4}$

$3x-2$

$\rule[225]{225}{2}$
