Eight less than seven times a number is six find the number

2

Step-by-step explanation:

let the number be n , then

7n - 8 = 6 ( add 8 to both sides )

7n = 14 ( divide both sides by 7 )

n = 2

The number is 2

10 you would take 50/ .2

step-by-step explanation:

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
