How do you solve
2/5x+10=0

x = -25

Step-by-step explanation:

Step 1: Write out equation

2/5x + 10 = 0

Step 2: Subtract 10 on both sides

2/5x + 10 - 10 = 0 - 10

2/5x = -10

Step 3: Multiply both sides by 5/2

5/2(2/5x) = -10(5/2)

x = -50/2

x = -25

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
