You are the shift supervisor at a local restaurant. You note that 15 employees work on Sundays. This represents 60% of all the
restaurant's employees.
How many employees does the restaurant have?

4x and 6y

im not sure though

only 10/60 isn't equivalent

hope this : )

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

126 maybe. sorry
