Leonardo is solving the equation 4(x-1/5)=2 2/3 his world is shown. where is his error

Step 3!!!

Step-by-step explanation:

8/3+4/5=

40/15+12/15 not 16/15

the solution is 12x-6y

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
