Answer 6

To identify the equation for which the order of steps is to first divide both sides by 2 and then to subtract 10 from both sides, we can analyze each option:

1. **Equation: 2x + 10 = 16**
- If we divide both sides by 2, we get:
\[
x + 5 = 8
\]
- Subtracting 5 gives:
\[
x = 3
\]
- This matches the required order of steps.

2. **Equation: 2(x + 10) = 16**
- Dividing both sides by 2:
\[
x + 10 = 8
\]
- Subtracting 10 gives:
\[
x = -2
\]
- This does not match the order.

3. **Equation: 10(x + 2) = 16**
- Dividing both sides by 10:
\[
x + 2 = 1.6
\]
- Subtracting 2 gives:
\[
x = -0.4
\]
- This does not match the order.

4. **Equation: 2(x − 10) = 16**
- Dividing both sides by 2:
\[
x - 10 = 8
\]
- Subtracting 10 gives:
\[
x = 18
\]
- This does not match the order.

Ultimately, the only equation where the order of steps is to first divide both sides by 2 and then subtract 10 is:

**2x + 10 = 16**.

Answer 7

To solve the equation \(-4(z + 12) = 36\) for \(z\), follow these steps:

1. **Divide both sides by -4:**
\[
z + 12 = \frac{36}{-4}
\]
\[
z + 12 = -9
\]

2. **Subtract 12 from both sides:**
\[
z = -9 - 12
\]
\[
z = -21
\]

Thus, the solution for \(z\) is **−21**.

Answer 8

The reference resource that best helps a reader determine the meaning of technical words in a text is a **glossary**. A glossary typically provides definitions of specialized terms used within a particular document or field.

So the correct response is: **glossary**.

Answer 9

The option that describes what a thesaurus is used for is **finding synonyms and antonyms of a word**. A thesaurus provides alternatives to words and helps writers find words with similar or opposite meanings.

So the correct response is: **finding synonyms and antonyms of a word**.

Answer 10

To find out how to pronounce the word "phylum," Wesley should consult **an online dictionary**. Online dictionaries typically provide pronunciation guides, including phonetic spelling and audio pronunciations.

So the correct response is: **an online dictionary**.

Answer 11

The best resource for Bryan to find a more interesting word to replace "cold" is **a thesaurus**. A thesaurus will provide him with synonyms that can help him find a more vivid or interesting alternative.

So the correct response is: **a thesaurus**.
