Question

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

\[
0.5r + 10s + 2
\]
