Group of answer choices

True

False

I chose true but I am not sure

Answer 1

Evaluate the expression and enter your answer in the box below.

9 - (-1)

Answer 2

Evaluate the expression and enter your answer in the box below.

7 x 3 - 7 + 24 x 3 - 5

Answer 3

Evaluate the expression and enter your answer in the box below.

1. -4 x (4 + 2) + 234 x 9


2. Evaluate the expression and enter your answer in the box below.

[(18 + 10) x 2] + 4 x (6 - 4)

Answer 4

umm those 2 were incorrect.

Answer 5

Your choice is correct. The statement "The absolute value of a number is always positive or 0" is true. The absolute value of a number represents its distance from zero on the number line, regardless of the direction, and thus it is never negative. Absolute values can be either positive or zero.

Answer 6

To evaluate the expression \( 9 - (-1) \), you can rewrite it as:

\[ 9 + 1 \]

This is because subtracting a negative number is the same as adding its positive counterpart.

Now, calculate:

\[ 9 + 1 = 10 \]

So, the answer is \( 10 \).

Answer 7

To evaluate the expression \( 7 \times 3 - 7 + 24 \times 3 - 5 \), follow the order of operations (which is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. First, perform the multiplications:
- \( 7 \times 3 = 21 \)
- \( 24 \times 3 = 72 \)

2. Now substitute back into the expression:
\[
21 - 7 + 72 - 5
\]

3. Next, perform the operations from left to right:
- \( 21 - 7 = 14 \)
- \( 14 + 72 = 86 \)
- \( 86 - 5 = 81 \)

So, the final answer is \( 81 \).

Answer 8

Let's evaluate each expression step-by-step.

### Expression 1:
\[ -4 \times (4 + 2) + 234 \times 9 \]

1. First, calculate the expression inside the parentheses:
\[
4 + 2 = 6
\]

2. Substitute back into the expression:
\[
-4 \times 6 + 234 \times 9
\]

3. Now, perform the multiplications:
\[
-4 \times 6 = -24
\]
\[
234 \times 9 = 2106
\]

4. Combine the two results:
\[
-24 + 2106 = 2082
\]

So, the answer for Expression 1 is **2082**.

---

### Expression 2:
\[ [(18 + 10) \times 2] + 4 \times (6 - 4) \]

1. First, calculate the expressions inside the parentheses:
\[
18 + 10 = 28
\]
\[
6 - 4 = 2
\]

2. Substitute back into the expression:
\[
[28 \times 2] + 4 \times 2
\]

3. Now, perform the multiplications:
\[
28 \times 2 = 56
\]
\[
4 \times 2 = 8
\]

4. Combine the two results:
\[
56 + 8 = 64
\]

So, the answer for Expression 2 is **64**.

**Final answers:**
1. Expression 1: **2082**
2. Expression 2: **64**

Answer 9

I apologize for the oversight. Let’s carefully reevaluate each expression step by step.

### Expression 1:
\[ -4 \times (4 + 2) + 234 \times 9 \]

1. **Evaluate inside the parentheses:**
\[
4 + 2 = 6
\]

2. **Now substitute back:**
\[
-4 \times 6 + 234 \times 9
\]

3. **Perform the multiplications:**
- \( -4 \times 6 = -24 \)
- \( 234 \times 9 = 2106\)

4. **Add the results:**
\[
-24 + 2106 = 2082
\]

**Result for Expression 1:** **2082** (Please double-check if there were specific contexts or rounding issues, but the math checks out.)

---

### Expression 2:
\[ [(18 + 10) \times 2] + 4 \times (6 - 4) \]

1. **Evaluate inside the parentheses:**
- For \( (18 + 10) \):
\[
18 + 10 = 28
\]
- For \( (6 - 4) \):
\[
6 - 4 = 2
\]

2. **Now substitute back:**
\[
(28 \times 2) + (4 \times 2)
\]

3. **Perform the multiplications:**
- \( 28 \times 2 = 56 \)
- \( 4 \times 2 = 8 \)

4. **Add the results:**
\[
56 + 8 = 64
\]

**Result for Expression 2:** **64**
