Jennifer had $24 to spend on five pens. after buying them she had $14. how much did each pen cost

Jennifer used $24-14=10 dollars in total.

The $10 was spend on five pens, each pen costing say, x, dollars.

The equation would be 10 = 5x

x = 10÷5= $2

So each pen costs $2 :)

Hope this helps! Feel free to ask below if you have any questions~ 

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
