-31-4=-5-25x-5

x = 1

Step-by-step explanation:

- 31 - 4 = - 5 - 25x - 5

− 3 5 = − 5 − 2 5 − 5

− 3 5 = − 2 5 − 1 0

− 3 5 + 1 0 = − 2 5 − 1 0 + 1 0

− 2 5 = − 2 5

− 2 5 = − 2 5

-25/-25 = - 25x/- 25

x = 1

X=1

Step-by-step explanation:

1)Subtract the numbers

-31-4=-5-25x-5

-35=-5-25x-5

2)Subtract the numbers

-35=-5-25x-5

-35=-10-25x

3)Rearrange terms

-35=-10-25x

-35=-10-25x

4)Add 10 to both sides of the equation

−35=−25−10

−35+10=−25−10+10

5)Simplify

−25=−25x

X=1

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
