Answer:
Discount percentage = 10.5% (Approx)
Therefore the discount is seller offering you is 10.5 % .
Step-by-step explanation:
Discount = Marked price - Selling price
As given
You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95 .
Here
Marked price = $19.95
Selling price = $17.85
Discount = 19.95 - 17.85
= $2.1


Discount percentage = 10.5% (Approx)
Therefore the discount is seller offering you is 10.5 % .
The answer is 6:15, but if u need to simplify the answer would be 2:5.
Answer is 10 and 170, complementary angles are 90°, while supplementary angles are 180 in total, if angle A is 80 then you subtract 90 by 80 and you get 10, so that is angle B, So then you are asked what is angle C. Which is part of the supplementary angle so you take the 10° that you got from B and then you subtract 180 by the 10, And thats how you get 170 and that's how you know that C is 170 (hope this explanation helps)
Let's say "c" is a constant, hmmmm any constant, for any value whatsoever of "x", "y" is always that constant, for example, say c = 3, thus y = 3, so a table for it will look like

now, if you plot those points, it'd looks like the picture below.
