3. Solve each inequality using the Subtraction Property of Inequality. \( \begin{array}{lll}\text { a. } x+8<20 & \text { b. } 19.5 \leq d+13.2 & \text { c. } v+20>7\end{array} \)

To solve these inequalities using the Subtraction Property of Inequality, we need to isolate the variable on one side. For the first inequality, \( x + 8 < 20 \), subtract 8 from both sides: \( x < 20 - 8 \) \( x < 12 \). For the second inequality, \( 19.5 \leq d + 13.2 \), subtract 13.2 from both sides: \( 19.5 - 13.2 \leq d \) \( 6.3 \leq d \) or \( d \geq 6.3 \). For the third inequality, \( v + 20 > 7 \), subtract 20 from both sides: \( v > 7 - 20 \) \( v > -13 \). So the solutions are: a. \( x < 12 \) b. \( d \geq 6.3 \) c. \( v > -13 \).
