Answer: Our required equation will be 
Step-by-step explanation:
Since we have given that
Base salary of Karen = $2000
Rate of commission on all of her sales = 20%
We need to write a equation:
Let the total salary of her be 's'
Let the number of dollars of merchandise sold be 'd'
According to question, it becomes

Hence, our required equation will be 
Answer:
No, they're not
Step-by-step explanation:
If two triangles have equal angles we can say they are similar, as u can see it doesn't apply for those triangle.
<h3>Answer:</h3>
7
<h3>Explanation:</h3>
The formula usually used for the sum of interior angles of an n-sided convex polygon is ...
... angle sum = 180°×(n -2)
In your case, angle sum is 900°, so this becomes
... 900 = 180(n -2)
... 5 = n -2 . . . . . . . . . divide by 180
... 7 = n . . . . . . . . . . . the polygon has 7 sides
_____
It may be easy to remember that the sum of exterior angles is always 360°, and each exterior angle adds to its corresponding interior angle to make 180°. Then, for n angles The sum of interior and exterior angles is n·180°. Subtracting the sum of exterior angles from this gives the sum of interior angles: n·180° -360° = 180°(n-2).
Twice, two times. Good luck with it all.
