Answer:6.1
Step-by-step explanation: the equation is 6n=30.5+n. the first thing you you do is subtract n on both sides which would be 6n-n which gives you 5. the equation now is 5n=30.5. now what you do is divide 5 on both sides so it would be 30.5/5 and that gives you 6.1
Answer:
We need to simplify the following expressio:
![\frac{1}{2} x^{2}- 4x-\frac{2}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20x%5E%7B2%7D-%204x-%5Cfrac%7B2%7D%7Bx%7D)
Multiply the whole expression by '2x':
![x^{3}-8x^{2}-4](https://tex.z-dn.net/?f=x%5E%7B3%7D-8x%5E%7B2%7D-4)
The expression can't be more simplified.
A(t)=P(1+r)t
A = accrued amount = what you are solving for
P = principle investment = $400
r = rate of growth = 5% = 0.05
t = time = 10 years
A(10) = 400(1.05)10 (use calculator to solve)
A(10) ≈ 4,200
Step-by-step explanation:
115 divided by 12
27 divided by 12
then add both of them there is your answer
