Answer:
Step-by-step explanation:
Let the number of months be x
Alligator 1 weight = 4 + 2x
Alligator 2 weight = 8 + x
- 4 + 2x = 8 + x
- 2x - x = 8 - 4
- x = 4
The answer is 4 months
4 consecutive odd numbers....x, x + 2, x + 4, x + 6
2(x + x + 2) = 3(x + 4 + x + 6) - 40
2(2x + 2) = 3(2x + 10) - 40
4x + 4 = 6x + 30 - 40
4x + 4 = 6x - 10
4x - 6x = -10 - 4
-2x = - 14
x = -14/-2
x = 7
x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13
ur numbers are : 7,9,11,13 <==
