How many solutions does 5(d+2)=3(d-6) ?

One solution

Step-by-step explanation:

This equation has 1 variable with a degree of 1, meaning that there's one solution.

5d+10=3d-18

2d=-28

d=-14

5 (d +2) = 3 (d —6)

Or 5d + 10 = 3d — 18

Or 5d —3d = —18 —10

Or 2d = —28

Or d = —28/2

Or d = —14

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

-1   1/6.   you dont subtract the denominators
