Which shows the best use of associative and commutative properties to make simplifying 1/6 - 8 + 3 - 5/6 + 9 easier? A. [1/6+(-8)] + [3+ (-5/6) + 9]
B. (3+1/6) + [9 + (-8) + (- 5/6)]
c. (1/6 - 5/6) + [3 + 9 + 9- (-8)]
d. [3 + 9 + 1/6] + [-5/6 + (-8)]

answer: the first graph

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: r there any options?

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
