Answer 2

To solve the given expression, let's break it down step by step:

1. $5.5 \times 30 - 5$ = $165 - 5$ = $160$

2. $30 + 5 \times 5.4$ = $30 + 27$ = $57$

3. $\frac{45}{5} \times 60 - 51$ = $9 \times 60 - 51$ = $540 - 51$ = $489$

4. $\frac{35}{5} \times 21 \div 3$ = $7 \times 21 \div 3$ = $147 \div 3$ = $49$

5. $\frac{30}{5} \times 24 \div 4$ = $6 \times 24 \div 4$ = $144 \div 4$ = $36$

6. $57 - 23 \times 6.5$ = $57 - 149.5$ = $-92.5$

Now, let's put it all together:

$160 + 57 + 489 + 49 + 36 - 92.5$

$= 699.5$

So, the final result is approximately $699.5$.
