The third side of the Triangle should be greater than the difference of other two sides, so
And, The third side should be less than the sum of other two sides that is ~
Considering these two inequalities, we get ~
Answer:
x=-5
Step-by-step explanation:
Vertical lines have the same x value all the time. They are of the form x=
Since it passes through the point (-5,-2) the x value must be -5
x=-5
So what you would do is you would divide 27 by 12. Your answer would be 2.25. They used 2.25 pounds per sandwich.

Answer: C) 45 dollars</h3>
========================================================
Explanation:
x = sticker price, which is some number larger than 9 (otherwise the store loses money)
x-9 = profit made per speaker
To get the gross margin percentage, we divide the profit over the sales (aka revenue). So we'll divide (x-9) over x
The expression (x-9)/x represents the gross margin in decimal form. Set this equal to 0.80 and solve for x
-----------------
(x-9)/x = 0.80
x-9 = 0.80x
x-0.80x = 9
0.20x = 9
x = 9/0.20
x = 45
The sticker price is $45
-------------------
If the sticker price is $45 per speaker, then the store owner gets 45-9 = 36 dollars in profit per speaker sold. The gross margin would be (profit)/(sales) = 36/45 = 0.80 = 80%
In other words, 80% of the revenue is profit (the remaining 20% is costs or expenses).
