Answer:
no solution
Step-by-step explanation:
Given
- 3 | 6n - 2 | + 5 = 8 ( subtract 5 from both sides )
- 3 | 6n - 2 | = 3 ( divide both sides by - 3 )
| 6n - 2 | = - 1
The absolute value always returns a positive value and so
| 6n - 2 | ≠ - 1
Hence there is no solution to the equation
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
