The model shows 5x-9=-3x+20
Solve for x:
5x-9=-3x+20
5x=-3x+29
8x=29
x=29/8

The boat will be worth $3,813.56 after 9 years.
Depreciation = beginning cost x depreciation rate
Ending cost = beginning cost - depreciation
Depreciation is the wear and tear of an object that decreases its value.</span></span></span></span>
Answer: 
Step-by-step explanation:
Let A be the event that the sum is 7 and and B be the event that the sum is 11 .
When two pair of dices rolled the total number of outcomes = 
The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}
Thus n(A)= 6
The sample space of event B = {(5,6), (6,5)}
n(B)=2
Since , both the events are independent , then the required probability is given by :-
Hence, the required probability =
