19*9 = 171
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
The final number in this sum would be 18: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 171

1 foot equals 12 inches; 171 inches equals 14 feet 3 inches. Or to leave the answer entirely in feet you can say that 171 inches equals 14 1/4 feet or 14.25 feet.
100 + 71 = 171, as does 99 + 72, 98 + 73, and so on.
-171 = 19x so x = -9
19*9 = 171
21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
171 x 56 = 9576
The final number in this sum would be 18: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 171
