i’m pretty sure the answer is 3
21 divided by 7 equals 3
letter d is one of the irrational numbers
B
Subtract 2x from the left side and the right side. Then you get -y = -2x+6. The divide each side by negative 1. Thus getting you to an answer of y = 2x-6
The mean is 32
The median is 67
Answer:
2 - sqrt(3)
Step-by-step explanation:
Split pi/12 into two angles where the values of the six trigonometric functions are known.
tan (pi/4 - pi/6)
Apply the difference of angles identity

tan(pi/4) = 1 , tan(pi/6) = (sqroot3)/3
