1. **State the problem:** We need to rewrite the expression $$-10m - (-7.6m + 1)$$ by distributing the minus sign outside the parentheses. 2. **Recall the rule:** When subtracting a group of terms inside parentheses, distribute the minus sign (which is equivalent to multiplying by $$-1$$) to each term inside. 3. **Apply distribution:** $$-10m - (-7.6m + 1) = -10m + \cancel{-}(-7.6m) + \cancel{-}(1)$$ Distributing the minus sign changes the signs inside: $$= -10m + 7.6m - 1$$ 4. **Combine like terms:** $$-10m + 7.6m = (-10 + 7.6)m = -2.4m$$ 5. **Write the final simplified expression:** $$-2.4m - 1$$ **Answer:** $$-2.4m - 1$$
