write and evaluate the expression. then, complete the statements. nine more than the product of seven and a number, decreased by three the expression to model the situation is the value of the expression when n = 8 is

Answer

Explanation:

Step1: Translate the description to an expression

Let the number be $n$. The product of seven and the number is $7n$. Nine more than this product is $7n + 9$, and decreased by three gives the expression $7n+9 - 3=7n + 6$.

Step2: Evaluate the expression when $n = 8$

Substitute $n = 8$ into the expression $7n+6$. We get $7\times8+6=56 + 6=62$.

Answer:

The expression to model the situation is $7n + 6$. The value of the expression when $n = 8$ is $62$.
