1.29 is 6.45 divided by 5
7. 18.3 divided by 4 is 4.575. 4.575 is closest to 4.5 which would be our answer
8. 14.6 divided by 3 is 4.86. If we round it, then it would be 5 which would be the answer
10. The answer to the problem would be 11.58
Answer:

Step-by-step explanation:
Normally, when I do this, I differentiate each term first with respect to x then with respect to y. In this solution, I differentiated the entire expression with respect to x, then with respect to y. That makes separating the dx and dy coefficients much easier, so the solution almost falls into your lap.
