To solve the problem we will find the number of videos bought by Jerome and the total cost of all the videos.
The system of equations that model this information are:
- 15 = x + y
- 164 = 18x + 9y.
<h2>Explanation</h2>
Given to us
- Total amount spent by Jerome = $164
- Total videos bought by Jerome = 15
- Number of classic videos bought = y
- Number of new release videos bought = x
- Cost of a classic video = $8
- Cost of a new release video = $19
<h3>Total cost of all new release videos</h3>
= Number of new releases bought x Cost of a new release video
![= x \times \$19\\ =19x](https://tex.z-dn.net/?f=%3D%20x%20%5Ctimes%20%5C%2419%5C%5C%0A%3D19x)
<h3>Total cost of all classic videos</h3>
= Number of classic videos bought x Cost of a classic video
![= y \times \$8\\ =8 y](https://tex.z-dn.net/?f=%3D%20y%20%5Ctimes%20%5C%248%5C%5C%0A%3D8%20y)
<h2>Total videos bought by Jerome</h2>
Total videos bought by Jerome
= Number of new releases bought + Number of classic videos bought
15 = x + y
<h2>Total amount spent by Jerome </h2>
Total amount spent by Jerome
= Total cost of all new release videos + Total cost of all classic videos
$164 = 19x + 8y
164 = 19x +8y
Hence, the system of equations that model this information are:
- 15 = x + y
- 164 = 18x + 9y.

Answer:
Step-by-step explanation:
Octagon is the figure with 8 sides and 8 angles
Sum of the exterior angles of any polygon is 360°
<u>Each angle of a regular octagon is:</u>
70 = 7 x 2 x 5
60 = 2² x 3 x 5
50 = 2 x 5²
LCM = 2 x 3 x 5 x 7 = 210
Answer: LCM = 210
