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:
   • \( 21 - 7 = 14 \)
   • \( 14 + 8 = 22 \)
   • \( 22 - 5 = 17 \)

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
