Please help thank you!

Answer 1

Let's evaluate each expression step by step.

### 1. Evaluate \( 7 \times 3 - 7 + \frac{24}{3} - 5 \)

1. Calculate \( 7 \times 3 \):
\[
7 \times 3 = 21
\]
2. Calculate \( \frac{24}{3} \):
\[
\frac{24}{3} = 8
\]
3. Substitute these values back into the expression:
\[
21 - 7 + 8 - 5
\]
4. Perform the operations from left to right:
- \( 21 - 7 = 14 \)
- \( 14 + 8 = 22 \)
- \( 22 - 5 = 17 \)

**Answer:** 17

### 2. Evaluate \( -4 \times (4 + 2) + \frac{234}{9} \)

1. Calculate \( 4 + 2 \):
\[
4 + 2 = 6
\]
2. Calculate \( -4 \times 6 \):
\[
-4 \times 6 = -24
\]
3. Calculate \( \frac{234}{9} \):
\[
\frac{234}{9} = 26
\]
4. Substitute these values back into the expression:
\[
-24 + 26
\]
5. Perform the addition:
\[
-24 + 26 = 2
\]

**Answer:** 2

### 3. Evaluate \( \left[ \frac{(18 + 10)}{2} \right] + 4 \times (6 - 4) \)

1. Calculate \( 18 + 10 \):
\[
18 + 10 = 28
\]
2. Calculate \( \frac{28}{2} \):
\[
\frac{28}{2} = 14
\]
3. Calculate \( 6 - 4 \):
\[
6 - 4 = 2
\]
4. Calculate \( 4 \times 2 \):
\[
4 \times 2 = 8
\]
5. Substitute these values back into the expression:
\[
14 + 8
\]
6. Perform the addition:
\[
14 + 8 = 22
\]

**Answer:** 22
