To solve for \( r \) in the equation \( 7(r + 1) = 20.3 \), we can follow these steps:
1. First, distribute the 7 on the left side of the equation:
\( 7r + 7 = 20.3 \)
2. Next, isolate the term with \( r \) by moving the constant term to the other side of the equation. We can do this by subtracting 7 from both sides:
\( 7r = 20.3 - 7 \)
\( 7r = 13.3 \)
3. To solve for \( r \), divide both sides by 7:
\( r = \frac{13.3}{7} \)
\( r \approx 1.9 \)
Therefore, the value of \( r \) that satisfies the equation \( 7(r + 1) = 20.3 \) is approximately 1.9.
