y = 3x+8 x + y = 72 x = 16 y = 56
Divide 72 by 3, this equals 24. This is the middle of the three numbers, so the answer is 23, 24 and 25. This works with finding any odd amount of consecutive numbers that sum up to another number.
The sum of three consecutive integers is -72
72.
L + S = 72 so L = 72 - S; 4L - 3S = 78 ie 4(72 - S) - 3S = 78 ie 288 - 4S - 3S = 78 ie 7S = 210 so S = 30 and L = 42. And there you have it!
72 - 3 = 69, 69/3 = 23 which is the smaller number. 23 x 2 = 46, 46 + 3 = 49 which is the larger number
82 + 8 = 64 + 8 = 72
12 and 60 ============ a + b = 72 a = 5b replacing a by 5b in the first equation 5b + b = 72 6b = 72 b = 12 72 - 12 = 60
to find the ratio divide the diameter by half.
The sum of the positive whole-number factors of 30 is 72.
