The formula for depreciation is:
Where x = Initial value,
y= Amount after depreciation.
r= Rate of depreciation,
t = time (in years)
According to given problem,
x = 1040, y= 944 and t = 12 months =1 year.
So, first step is to plug in these values in the above formula, So,
944 = 1040 (1 -r)
Divide each sides by 1040.
0.907692308 =1 - r
0.907692308 - 1 = -r Subtract 1 from each sides.
-0.092307692 = -r
So, r = 0.09 or 9%.
Now plug in 0.09 in the above equation to get the depreciation equation. So,
So, 
b) To find the value of the bike after 5 months,
plug in t = 5 months= 5/12 = 0.41667 years in the above equation of depreciation.
So, 
y = 1040 * 0.961465659
y = 999.9242852
y = 1000 (Rounded to nearest integer).
Hence, the value of the bike after 5 months is $1000.

Answer:
42 feet
Step-by-step explanation:
First let know what is
Yards to Feet
Note that;
1 Yard ⇒ 3 Feet
Thus, Formula: Multiply the length value by 3
Given:
Lena bought 14 yards of ribbon. How many feet of ribbon did she buy?
Therefore, 14 * 3 = 42
Hence, Answer is Lena brough 42 feet of ribbon.

Answer:
- equation: (x-3) +(x-1) +(x+1) +(x+3) = -72
- values: -21, -19, -17, -15
Step-by-step explanation:
When dealing with consecutive integers, it often simplifies the problem to work with their average value. We know the average value of the integers in this problem is the even integer between the middle two. We can call it x, and write the equation ...
(x-3) +(x-1) +(x+1) +(x+3) = -72
This simplifies to ...
4x = -72 . . . . . . . we knew this before we wrote the above equation, since the sum of 4 numbers is 4 times their average.
x = -18 . . . . . . . . the middle number of the sequence
So, the numbers are:
- -18-3 = -21
- -18-1 = -19
- -18+1 = -17
- -18+3 = -15
_____
A more conventional approach is to define the variable as the integer at one end or the other of the sequence. If we make it be the lowest number, then the equation is ...
(x) +(x +2) +(x +4) +(x +6) = -72
and that simplifies to ...
4x +12 = -72 . . . . . collect terms
4x = -84 . . . . . . . . subtract 12
x = -21 . . . . . . . . . . divide by 4
Now, the other three numbers are found by adding 2, 4, and 6 to this one.
