If x is equal to 52 and y is equal to 10,
then what is the value of x - 12y?

-68

Step-by-step explanation:

x-12y

52-12x10

52-120

-68

-68

Step-by-step explanation: if x is equal to 52 and y is equal to ten you have to plug in the numbers for the variables so your equation comes out to 52-12*10 which simplifies to 52-120 which equals -68

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
