Answer:
Justice lived in Germany for 15 months and he lived in Holland for 9 months.
Step-by-step explanation:
1. You must make a system of equations:
Where 
is the number on months he lived in Germany and 
is the number on months he lived in Holland.
2. You can solve this system of equations by using the Elimination Method. If you multiply the first equation by -120, you can cancel the variable when you add both equations, and then you can calculate . When you obtain the value of , you can substitute it into one of the original equations and solve for . Then:
Beau can make 48 bags of 1 ounce trail mix because a pound equals 16 ounces so you multiply 16 times the 3 pounds she has.
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.
So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.
