Final answer:
To simplify the expression 1/4m + 3/4m - (m + 1), combine like terms and distribute the negative sign. The answer is d. m - 1.
Step-by-step explanation:
To simplify the expression 1/4m + 3/4m - (m + 1), we need to combine like terms and perform the arithmetic operations in the correct order.
First, we can simplify the terms with the variables. 1/4m + 3/4m is equal to (1/4 + 3/4)m, which is (4/4)m or just 1m.
Next, we distribute the negative sign to (m + 1) to get -m - 1.
Finally, we combine the simplified terms 1m and -m to get 1m - m, which simplifies to just m. And we also subtract 1, so the expression is equivalent to m - 1.
Therefore, the answer is d. m - 1.
