Answer:
5 * 1.15ⁿ
Step-by-step explanation:
The equation would be
a1(r)^(n-1)
Now put it all together
A15= 5(1.15)^(15-1)
Count the rest and add the towns each
A15= 35.38
35 villagers now
Now you will find the equation 1
an=5(1.15)^(n-1)
So it going to equal 5 * 1.15ⁿ

Answer: x = 13.4
Step-by-step explanation:
We translate 'English' to 'math':
'decreased by' is subtraction
'is' means '='
12(x - 10) = 2x + 14
12x - 120 = 2x + 14
subtract 2x from each side
10x - 120 = 14
Add 120 to each side
10x = 134
Divide by 10 , to isolate the 'x'
x = 13.4
If we substitute 13.4 for 'x' back in the first equation, we get 40.8 for each side, so the equation balances.
I hope this helps.
