Evaluate the expression for s = 0.5. Write your answer as a decimal or whole number. 8.4s + 12.6 = _____

Identify expression: Identify the expression to be evaluated. We are given the expression 8.4s + 12.6 and the value of s as 0.5. We need to substitute s with 0.5 in the expression.Substitute with 0.5: Substitute s with 0.5 in the expression. Replace s with 0.5 in the expression 8.4s + 12.6 to get 8.4 * 0.5 + 12.6.Multiply and add: Multiply 8.4 by 0.5. Perform the multiplication: 8.4 * 0.5 = 4.2.Add 12.6 to the result from Step 3. Now, add 4.2 to 12.6 to get the final result: 4.2 + 12.6 = 16.8.

8.4s + 12.6 =

_____

Identify expression: Identify the expression to be evaluated. $\newline$ We are given the expression $8.4s + 12.6$ and the value of $s$ as $0.5$ . We need to substitute $s$ with $0.5$ in the expression.
Substitute with $0$ . $5$ : Substitute $s$ with $0.5$ in the expression. $\newline$ Replace $s$ with $0.5$ in the expression $8.4s + 12.6$ to get $8.4 \times 0.5 + 12.6$ .
Multiply and add: Multiply $8.4$ by $0.5$ . Perform the multiplication: $8.4 \times 0.5 = 4.2$ .
Multiply and add: Multiply $8.4$ by $0.5$ . Perform the multiplication: $8.4 \times 0.5 = 4.2$ . Add $12.6$ to the result from Step $3$ . Now, add $4.2$ to $12.6$ to get the final result: $4.2 + 12.6 = 16.8$ .
