Mary scored 28 points, which is twice as many points as Lashawna scored. Let L represent the points Lashawna scored.

Lashawna scored 14 points

Step-by-step explanation:

Let M = Mary's score

L = Lashawna score

M = 28 points

And M is twice as much as L score

M= 2L

L= M/2

L= 28/2

M = 14.

Lashawna score was 14 points

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
