Write 9 fewer homeruns than three and one-half the number of Diego's homeruns as an algebraic expression. Use \( d \) as your variable. \( ++-x \div\left|\begin{array}{llll}\square & \square^{0} & \sqrt{\square} & \square \sqrt{\square}\end{array}\right|=z<>\leq \geq \mid \) (a) \( \mid \pi \)

To express "9 fewer homeruns than three and one-half the number of Diego's homeruns," you would first calculate three and one-half of Diego's homeruns, which is \( \frac{7}{2}d \). Then, subtracting 9 gives you the expression: \( \frac{7}{2}d - 9 \). Now, to clarify the algebraic manipulations, be wary of the order of operations! Always resolve inside parentheses first and remember to apply any negative signs carefully, as missing these can lead to incorrect results. Converting fractions can also trip you up if you're not careful. So, double-check your calculations for accuracy!
