Distribute
n+4n-10=20

Combine like terms
5n-10=20

Add 10 to both sides

Explain why the amount of money in the account at the end of t years is given by the formula:

nevsk [136]

Answer:

Step-by-step explanation:

The initial amount invested is P0

Say it is compounded periodically either quarterly or monthly or semi annually with interest r%

If for a period interest is r%

Then after first period principal = principal+simple interest

= $P_{0}+\frac{P_{0}r }{n}$

where n is the no of times in a year it is compounded. n = 4 if quarterly, 12 if annually, etc

At the end of II period we have

Principal = $P_{0}+\frac{P_{0}r }{n}$

So for interest again the process is repeated

Thus we repeat this nt times which result in power with nt

Hence the formula

The second of 2 numbers is 7 times the first. Their sum is 32. Find the numbers. (With steps)

Vitek1552 [10]

Let's say "the second number" is y so y= 7(x) And x+y= 32
you would plug in y=7x into x+y=32 and that would look like this....x+7x=32
then you would add the x's and that would look like.... 8x=32 then you would divide 32/8 and get x =4 to find y, you just plug in x=4 into x+y=32
but I did most of the work so you can find y ;)
its not that hard... im sure you can do that;))))
