Answer 3

To calculate the expression 55d - 30d - 16d when d = 721, we substitute the value of d into the equation:

55d - 30d - 16d

Now we replace d with 721:

55 * 721 - 30 * 721 - 16 * 721

Calculating each part of the equation:

39655 - 21630 - 11536

Now we subtract the second and third terms:

39655 - 21630 - 11536 = 649

Therefore, when d = 721, the expression 55d - 30d - 16d equals 649.
