Using long division, we get
2x-5
x+3 | 2x^2+x-15
- (2x^2+6x)
_________
-5x-15
-(-5x-15)
________
0
2x-5 is your answer
3 for 3.60 the unit price come out to 1.20
25 x 2= 50, so the third grade dash is 50 meters long.
40+19.95x-59.85=59.85+29.95x-179.7
This is the problem solve it algebraically.

Answer:
a. -0.01 < x - 8 < 0.01
b. 7.99 < x < 8.01
c. see attachment
d. Bolt has to be greater than 7.99 mm and less than 8.01 mm to be within the margin of error of 0.01 mm.
Step-by-step explanation:
-0.01 < x - 8 < 0.01
-0.01 < x - 8 and x - 8 < 0.01
7.99 < x x < 8.01
Write this as: 7.99 < x < 8.01
On graph the 7.99 and 8.01 are very near to each other and represented via open red circle.
