Answer:
The correct answer is C. 4b^2+10b
3x/6 +1 = 7
Subtract 1 from each side:
3x/6 = 6
Multiply both sides by 6:
3x = 36
Divide both sides by 3:
X = 36 / 3
X = 12
Are you asking for it being simplified?
Answer: in explination
Step-by-step explanation:
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
annual interest = .05(4000) = 200
to double, you need another $4000
number of years = 4000/200 = 20
it will take 20 years
to check if you are right you would...
Check:
simple interest on $4000 for 20 years at 5%
= .05(20)(4000) = 4000
the amount = what we had + new amount
= 4000 + 4000 = 8000 which is double what we started with
So the answer would be it took 20 years.
