24.

25. 6

Step-by-step explanation:

For number 24:

To simplify this down, we can break it up into this:

3 divided by -2 is , x over x is just 1, and z over 1 is z.

So .

For number 25:

If we know the value of y and z we can just substitute inside the equation.

A negative divided by a negative is the same as a positive over a positive.

Hope this helped!

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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
