Answer:
A) z
Step-by-step explanation:
(8z - 10) ÷ (-2) + 5(z - 1)
1. Rewrite:
[tex]\large \textsf{$\dfrac{(8x-10)}{-2}+5(z-1)$}[/tex]
2. Distribute 5
[tex]\large \textsf{$5(z-1)$}\\\\\large \textsf{$5(z)+5(-1)$}\\\\\large \textsf{$5z-5$}[/tex]
Now we have:
[tex]\large \textsf{$\dfrac{(8x-10)}{-2}+\large \textsf{$5z-5$}$}[/tex]
3. Reduce the fraction:
[tex]\large \textsf{$\dfrac{(8x-10)}{-2}+\large \textsf{$5z-5$}$}\\\\\large \textsf{$-4x+5+5z-5$}[/tex]
4. Combine like terms:
[tex]\large \textsf{$-4x+5+5z-5$}=\large \textsf{z}[/tex]
Final answer: z
