Answer 2

It seems like you have provided an expression with multiple terms and parentheses. To simplify this expression, we can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's simplify the given expression step by step:

1. Start with the innermost parentheses: a. (1/2m + 3/4) → You can't simplify this further unless you have specific values for 'm'.

2. Next, deal with the expression inside the second set of parentheses: b. (2 1/2 - m) → If this is meant to be a subtraction, it's unclear what '2 1/2' means. If it's '2.5', then it becomes (2.5 - m).

3. Now, combine the results from steps 1 and 2: (1/2m + 3/4) + (2 1/2 - m)

4. Distribute the 5 to each term inside the next set of parentheses: 5(15x + 2y) + 4 - 3y

5. Simplify further if possible: a. 5 times 15x is 75x. b. 5 times 2y is 10y.

Now, your expression becomes:

(1/2m + 3/4) + (2 1/2 - m) + 75x + 10y + 4 - 3y

Remember that some parts of the expression may still need further simplification or evaluation depending on the specific value of 'm' and the meaning of '2 1/2'. If you can provide more context or specific values, I can help simplify it further.
