Answer 1

Let's evaluate each question step by step:

### Question 1: Are these like terms?
**2/3 b and 3.4 t**

**Answer:** False
- Like terms have the same variable component. Here, 'b' and 't' are different variables, so these are not like terms.

---

### Question 2: Are these like terms?
**-7.7jk and 3jk**

**Answer:** True
- Both terms contain the variable component 'jk', so they are like terms.

---

### Question 3: Simplify the expression by combining like terms.
**5x + 4x + 12 + 8x + 2**

Combining like terms:
- **5x + 4x + 8x = 17x**
- **12 + 2 = 14**

So the simplified expression is **17x + 14**.

**Answer:** 17x + 14

---

### Question 4: Evaluate the expression if **y = -6 and w = 4**
**y + w**

Substituting the values:
**y + w = -6 + 4 = -2**

**Answer:** -2

### Question 5: Match like terms.
1. **-5** - This is a constant term.
2. **3/5h** - This is a single-variable term, no match here.
3. **1/3mn** - This is a two-variable term, no match here.
4. **-9** - This is a constant term. Matches with -5 (if we consider just constants).
5. **2/5gh** - This is a two-variable term, no match here.
6. **-3gh** - This is a two-variable term, no match here.
7. **3.5** - This is a constant term. Matches with -5 and -9.
8. **1.2g** - This is a single-variable term, no match here.
9. **-8g** - This is a single-variable term, no match elsewise.
10. **6.7mn** - This is a two-variable term, no match elsewhere.

Without clearer pairing guidelines, if matching constants directly is the goal:

Matches can be designated as:
- -5 matches with -9 and 3.5.

The matching of other terms would need more context or structure showing what terms to match specifically.

If you need a detailed format of matched terms, please clarify further. Otherwise, I've provided a thorough breakdown of individual evaluations here!
