1. The problem asks for "5 times a number d." This means we want to express the product of 5 and the variable $d$. 2. The formula for multiplying a number by a variable is simply the number times the variable: $$5 \times d$$ 3. We can write this more simply as $$5d$$ which means 5 multiplied by $d$. 4. So, "5 times a number d" is expressed as $$5d$$. This is the final expression representing 5 times the number $d$.
