Final Answer:
The value of 9.3V + 8.7W when V=7 and W=8 is 134.7.
Step-by-step explanation:
To evaluate the expression 9.3V + 8.7W, substitute V=7 and W=8 into the expression:
9.3×7+8.7×8
Calculate each term separately:
65.1+69.6
Add the two values to get the final result:
134.7
Therefore, 9.3V + 8.7W, when V=7 and W=8, is equal to 134.7.
This type of calculation is fundamental in algebra and real-world applications, allowing us to determine the value of a given expression based on specific values assigned to the variables. In this case, the expression involves multiplying constants by variables and summing the results, showcasing the basic principles of algebraic evaluation.
The options provided can be compared to the calculated value to confirm the accuracy of the result. In this case, the correct option is not explicitly given, but the calculated value of 134.7 does not match any of the options exactly. Therefore, the closest option is not among the provided choices, emphasizing the importance of precise calculations in mathematical evaluations.
