Hello!
First you find the common difference in the sequence
6 - 12 = -6
0 - 6 = -6
The common difference is -6
We can now make the equation
-6(n - 1) + 12
we got the 12 because it is the first number in the sequence
Simplify
-6n + 6 + 12
Simplify
18 - 6n
The answer is B) an = 18 - 6n
Hope this helps!
Answer:
H=38
Step-by-step explanation:
The number of solutions of the equations can't be determined.
<h3>How to illustrate the information?</h3>
It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.
From the information, 3(5x + 2) = 15x
15x + 6 = 15x
Collect like terms
15x - 15x = - 6
0 = -6
Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.

Answer:
The interest rate is 7.5%
Step-by-step explanation:
You get the difference from the new number and the original. In this case, it is 30.96. I then divided the original by 30.96. The answer turned out to be .15. I doubled checked my answer by timing the original by .15 and adding it. But, I had to divide .15 by 2 so I could get the amount per year. So, it would be 7.5% per year of interest.
Answer:
Step-by-step explanation:
<u>Change in population:</u>
- 9800 - 6300 = 3500 (decrease)
<u>Percent change:</u>
- 3500/9800*100% = 35.7% (rounded to the nearest tenth)
