Answer:
x < -6
Step-by-step explanation:
-2x - 4 > 8
Add left and right of the > sign by 4.
-2x -4 +4 > 8 +4
-2x +0 > 12
-2x > 12
Divide left and right of the > sign by MINUS 2, and remember that will flip the sign!
(-2/-2)x < (12/-2)
x < -6
All angles in a triangle add up to 180
180 = 9 + 15 + 2x - 1 + 3x
180 = 24 - 1 + 2x + 3x
180 = 23 + 5x
180 - 23 = 5x
157 = 5x
Divide both sides by 5
X = 31.4 or 157/5
Pi/3 - pi/6
Adding or subtracting radians is solve the same way we add and subtract fractions.
1st step, find the least common denominator of the fractions.
3: 3, 6
6: 6 LCD is 6.
Multiply each fraction by a fraction that will result of a denominator of 6.
pi/3 * 2/2 = 2pi/6
pi/6 * 1/1 = pi/6
2pi/6 - pi/6 = (2pi - pi) / 6 = pi/6
So, pi/3 - pi/6 = pi/6.
