Answer:
Thus to rent <u>10</u> number of videos to get the cost same.
Step-by-step explanation:
Given:
Michael's Video charges member $4 to rent each video. If you get a store membership it costs $20 and members only pay $2 to rent a video.
Now, to find the number of videos to get the cost same.
Let the number of videos to get the cost same be
Charges to rent each video without membership = $4.
Cost of membership = $20.
Charges to rent each video with membership = $2.
Now, to get the number of videos to get the cost same we write and solve an equation:
<em>Subtracting both sides by </em><em> we get:</em>
<em /><em />
<em>Dividing both sides by 2 we get:</em>
Therefore, to rent 10 number of videos to get the cost same.
4.5 times 2.2 = 9.9
15.5-9.9= 5.6
5.6/3 can be written as 1 and 13/15
Do 85,608/12 and you should have your answer. hope this helps

Answer: 7, 4, 1, -2, -5</h3>
=========================================================
Explanation:
The notation a(1) = 7 means that the first term is 7
The second term would be a(2) and so on.
To get a(2), we plug in n = 2 to find that...
a(n) = a(n-1) - 3
a(2) = a(2-1) - 3
a(2) = a(1) - 3
a(2) = 7 - 3
a(2) = 4
The second term is 4. We find this by subtracting 3 from the first term.
To get the third term, we repeat the same set of steps but now use n = 3
a(n) = a(n-1) - 3
a(3) = a(3-1) - 3
a(3) = a(2) - 3
a(3) = 4 - 3
a(3) = 1
This process is repeated as much as you want to generate as many terms as you want.
In short, you subtract 3 from each term to get the next term. This implies that we have an arithmetic sequence with starting term 7 and common difference -3.
So that's how we end up with the first five terms: 7, 4, 1, -2, -5
