Answer:
the answer is ( there is no real solutions) i hoped this help if you need an explanation why let me know :)
A polygon must have at least 3 sides, but a curved angle isn't a side. This would result in you getting an oval. In short, it would not be a polygon. Hope this helps!
X= -12.5 you add (4+3) then, you combine it with 18 to get 25, then you divide 25 by -2x
The number of classes Anna can take so the total cost for the month will be the same is 5.
The monthly cost would be $37.50.
<h3>When would the total cost be the same?</h3>
When the monthly cost is equal, both equations would be equal: 7.5x = 5.5x + 10
In order to determine the value of x, take the following steps:
- Combine similar terms: 7.5x - 5.5x = 10
- Add similar terms: 2x = 10
- Divide both sides by 2 : 10 /2 = 5
Monthly cost when the cost is the same: 7.5 x 5 = $37.50
