24. 1st one
Step-by-step explanation:
the X cancals out the x leaving the z so it is the 1st one
Answer:
24. [tex]-\frac{3}{2} z[/tex]
25. 6
Step-by-step explanation:
For number 24:
To simplify this down, we can break it up into this:
[tex]\frac{3}{-2} \cdot \frac{x}{x} \cdot \frac{z}{1}[/tex]
3 divided by -2 is [tex]-\frac{3}{2}[/tex], x over x is just 1, and z over 1 is z.
So [tex]-\frac{3}{2} z[/tex].
For number 25:
If we know the value of y and z we can just substitute inside the equation.
[tex]\frac{-18}{-3}[/tex]
A negative divided by a negative is the same as a positive over a positive.
[tex]18\div3=6[/tex]
Hope this helped!
