Write an equivalent expression by distributing the "minus−" sign outside the parentheses:

Question

0, point, 5, r, minus, left parenthesis, minus, 10, s, minus, 2, right parenthesis
0.5r−(−10s−2)

Answer 1

To distribute the minus sign outside the parentheses in the expression \( 0.5r - (-10s - 2) \), you need to apply the distribution:

1. 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:

\[ 0.5r + 10s + 2 \]
