Evaluate the expression for q = 3.8 and r = 2.4. Write your answer as a decimal or whole number. qr − r = _____

Identify Expression: Identify the expression to be evaluated. The given expression is qr − r. We need to substitute q = 3.8 and r = 2.4 into this expression.Substitute Values: Substitute the given values into the expression. Replace q with 3.8 and r with 2.4 in the expression qr − r. Expression: (3.8 * 2.4) − 2.4Perform Multiplication: Perform the multiplication. Multiply 3.8 by 2.4. 3.8 * 2.4 = 9.12Subtract from Result: Subtract r from the result of the multiplication. Subtract 2.4 from 9.12. 9.12 − 2.4 = 6.72

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ The given expression is $qr - r$ . We need to substitute $q = 3.8$ and $r = 2.4$ into this expression.
Substitute Values: Substitute the given values into the expression. $\newline$ Replace $q$ with $3.8$ and $r$ with $2.4$ in the expression $qr − r$ . $\newline$ Expression: $(3.8 \times 2.4) − 2.4$
Perform Multiplication: Perform the multiplication. $\newline$ Multiply $3.8$ by $2.4$ . $\newline$ $3.8 \times 2.4 = 9.12$
Subtract from Result: Subtract $r$ from the result of the multiplication. $\newline$ Subtract $2.4$ from $9.12$ . $\newline$ $9.12 - 2.4 = 6.72$
