Short Answer

Justify each statement with a property from algebra or property of congruence.
If $2 z - 5 = - 3$ then $2 z = 2$ .

From the property of Algebra, it is proved that $2 z = 2$ .

TABLE OF CONTENTS

Step 1. Apply subtraction property of algebra.

If $a = b$ and $c = d$ , then $a - c = b - d$ .

Step 2. Description of step.

Add 5 on both sides of the equation $2 z - 5 = - 3$ .

$2 z - 5 + 5 = - 3 + 5$

Step 3. Description of step.

Simplify the equation mentioned in step 2 to find the value of 2z.

$\begin{matrix} 2 z + 0 = 2 \\ 2 z = 2 \end{matrix}$

Therefore, the value of $2 z$ is 2.

Provide a counterexample to show that each statement is false. You may use words or draw a diagram.

If a number is divisible by 4, then it is divisible by 6.

State the number that is paired with the bisector of $∠ C D E$ .

Consider the following statements:

Reflexive Property: Robot A is as rusty as itself.

Symmetric Property: If Robot A is as rusty as Robot B, then Robot B is as rusty as Robot A.

Transitive Property: If Robot A is as rusty as Robot B and Robot B is as rusty as Robot C, then Robot A is as rusty as Robot C.

A relation such as “is as rusty as” that is reflexive, symmetric, and transitive is an equivalence relation. Which of the following are equivalence relations?

a. Is rustier than

b. Has the same length as

c. Is opposite (for rays)

d. Is coplanar with (for lines)

Justify each step.

$15 y + 7 = 12 - 20 y$

$35 y + 7 = 12$

$35 y = 5$

$y = \frac{1}{7}$
