(x-6)/2 = x+13
x-6 = 2x + 26
x = -6-26 = -32
ONE SOLUTION.
2+6x-7 = 8+2x-10+4x
-5 + 6x = -2 + 6x
-5 = -2
This is not possible for any value of x ,
so NO SOLUTION
3x+5 = 1/5 (15x+10)
3x+5 = 3x+ 2
5 = 2
This is not possible for any value of x ,
so NO SOLUTION
1/4 (16+8x)= 3x-1-x+5
4 +2x = 2x +4
this is true for all values of x,
so, INFINITE SOLUTIONS.
Answer:
See Below
Step-by-step explanation:
The question is asking:
After how many years, 20,000 will become 500,000 at an annual interest of 11.5%?
So, we need compound growth formula shown below to solve this:
F is future value
P is present amount
r is rate of interest
t is the time of year
Given,
F = 500,000
P = 20,000
r = 11.5% = 11.5/100 = 0.115
t is what we want to find
Now, we take natural log of both sides and solve for t:
Its is going to take about 29.57 years, rounding, 30 years
