Pl s confused

molly earns a rebate each month on her movie tickets and books. she earns $0.25 for each movie ticket and $2 for each book. last month molly purchased 4 movie tickets and earned $17.

part a: create an equation that will determine the number of books she purchased. (3 points)

part b: solve this equation justify

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

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
