Tanisha bought 2 skirts and 3 pairs of pants for $220. A week later she bought 1 skirt and 3 pairs of pants, at the same prices, for $185. How much is each skirt?

220.00

-185.00

= 35.00 the difference of what was paid at the same prices.

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
