Candice bought 4 notebooks that each cost the same amount. She paid with a $20 bill and received $10.32 in change. Write an equation that can be used to find x, the cost of each notebook.

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

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

what statement? is there an image?
