Question

Simplify (8z - 10) ÷ (-2) + 5(z - 1).
OZ
OZ-1
Oz-2

Answer 1

A) z

Explanation:

(8z - 10) ÷ (-2) + 5(z - 1)

1. Rewrite:

`\large \textsf{$((8x-10))/(-2)+5(z-1)$}`

2. Distribute 5

`\large \textsf{$5(z-1)$}\\\\\large \textsf{$5(z)+5(-1)$}\\\\\large \textsf{$5z-5$}`

Now we have:

`\large \textsf{$((8x-10))/(-2)+\large \textsf{$5z-5$}$}`

3. Reduce the fraction:

`\large \textsf{$((8x-10))/(-2)+\large \textsf{$5z-5$}$}\\\\\large \textsf{$-4x+5+5z-5$}`

4. Combine like terms:

`\large \textsf{$-4x+5+5z-5$}=\large \textsf{z}`

Final answer: z
