Evaluate the expression for p = 3.9 and q = –3. Write your answer as a decimal or whole number. pq − q = _____

Identify Expression: Identify the expression to be evaluated. The given expression is pq − q. We need to substitute p = 3.9 and q = –3 into this expression.Substitute Values: Substitute the given values into the expression. Substitute p = 3.9 and q = –3 into pq − q to get (3.9)(–3) − (–3).Perform Multiplication: Perform the multiplication. Multiply 3.9 by –3 to get –11.7. So, the expression becomes –11.7 − (–3).Simplify Expression: Simplify the expression by subtracting q. Subtracting a negative is the same as adding the positive equivalent, so –11.7 − (–3) becomes –11.7 + 3.Perform Addition: Perform the addition. Add –11.7 and 3 to get –8.7.

q = -3

\newline

Write your answer as a decimal or whole number.

\newline

pq - q =

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ The given expression is $pq - q$ . We need to substitute $p = 3.9$ and $q = -3$ into this expression.
Substitute Values: Substitute the given values into the expression. $\newline$ Substitute $p = 3.9$ and $q = -3$ into $pq - q$ to get $(3.9)(-3) - (-3)$ .
Perform Multiplication: Perform the multiplication. $\newline$ Multiply $3.9$ by $-3$ to get $-11.7$ . $\newline$ So, the expression becomes $-11.7 - (-3)$ .
Simplify Expression: Simplify the expression by subtracting $q$ . Subtracting a negative is the same as adding the positive equivalent, so $–11.7 − (–3)$ becomes $–11.7 + 3$ .
Perform Addition: Perform the addition. $\newline$ Add $-11.7$ and $3$ to get $-8.7$ .
