Substituting values v=6 and w=7 into the expression 10.5v + 9.9w results in 124.8, confirming option A as the correct answer.
To find the result of the expression \(10.5v + 9.9w\) when v = 6 and
w = 7, substitute these values into the expression:
10.5(6) + 9.9(7)
Calculate each term:
63 + 69.3
Combine the results:
124.8
Therefore, when v = 6 and w = 7, the result of 10.5v + 9.9w is 124.8. Among the provided options A. 124.8 is the correct choice.
