Answer 1

Let's evaluate each expression step by step:

### Question 1:
Evaluate the expression \( \frac{5x - 4y}{2} \) when \( x = 8 \) and \( y = 4 \).

1. Substitute \( x \) and \( y \):
\[
\frac{5(8) - 4(4)}{2} = \frac{40 - 16}{2} = \frac{24}{2} = 12
\]

**Response:** 12

---

### Question 2:
Evaluate the expression \( 8 + \frac{3a}{2b} \) when \( a = 4 \) and \( b = 2 \).

1. Substitute \( a \) and \( b \):
\[
8 + \frac{3(4)}{2(2)} = 8 + \frac{12}{4} = 8 + 3 = 11
\]

**Response:** 11

---

### Question 3:
Evaluate the expression \( \frac{10p - 4m}{5} \) when \( m = 10 \) and \( p = 5 \).

1. Substitute \( m \) and \( p \):
\[
\frac{10(5) - 4(10)}{5} = \frac{50 - 40}{5} = \frac{10}{5} = 2
\]

**However, it seems there might be a misunderstanding in the responses since none of the options match. Let's find the correct response with another look.**

**Final Response would subtract correctly:**
\[
10(5) = 50 \quad \text{and} \quad -4(10) = -40 \\
50 - 40 = 10 \\
\frac{10}{5} = 2
\]

While we computed correctly for 10, 2 is not an option.

Here, for completeness of information, it is important to note that without proper options, the assessment stands with found calculations.

So the final answers are:
1. 12
2. 11
3. 2 (but no correct option provided).
