To distribute the minus sign outside the parentheses in the expression \( 0.5r - (-10s - 2) \), you need to apply the distribution:
- Change the \( - \) to \( + \) for each term inside the parentheses:
- \( -(-10s) \) becomes \( +10s \)
- \( -(-2) \) becomes \( +2 \)
So, distributing the minus sign gives you:
\[ 0.5r + 10s + 2 \]
Thus, the equivalent expression is:
\[ 0.5r + 10s + 2 \]
