Which equations describe the relationship between the number of minutes Diana runs, r, and the number of minutes she lifts weights, w. Select all that apply. 12 + w = r

r = w − 12

w = 12 + r

r − 12 = w

r + w = 12

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
