-y = -3x-2
/-1 /-1
_________
y = 3x+2
Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
Answer:
-270 to -360 degrees I quadrant
And for this case since -300° is between -270 to -360 degrees we can conclude that this angle is in the I quadrant
Step-by-step explanation:
For this case we can solve this problem taking in count the following rule when we have negative angles:
0 to -90 degrees IV quadrant
-90 to -180 degrees III quadrant
-180 to -270 degrees II quadrant
-270 to -360 degrees I quadrant
And for this case since -300° is between -270 to -360 degrees we can conclude that this angle is in the I quadrant
Total number of pairs = 24 pairs.
Total cost of 24 pairs = $800 approximately.
Cost of each pair = 
Plugging values in the above formula, we get
Cost of each pair = 
If we divide 800 by 24, we get 33.33 approximately.
But in the given problem, estimated cost is given $28 per pair.
If we subtract 33.33-28, we get $5.33.
So, the estimated cost is $5.33 each pair less than the actual cost of each pair.
Therefore, $28 per pair is not a good estimate of the price.
