Answer:

Correct choice is (C). 4z^5.

Step-by-step explanation:

Given expression is -3z^5-\left(-7z^5\right).

Now we need to simplify that then select the correct difference value from the given choices.

-3z^5-\left(-7z^5\right)

negative times negative is positive

=-3z^5+7z^5

Combine like terms because variable z has same exponent.

=(-3+7)z^5

=4z^5

Hence correct choice is (C). 4z^5.

meriva

Answer:

  16%

Step-by-step explanation:

The additional wage amount is $80.

The original wage amount is $500.

The ratio of the two is ...

  $80/$500 = 0.16 = 16/100

To express that ratio as a percentage, multiply it by 100%.

  0.16 × 100% = 16%

_____

It might help you to think of the percent sign (%) as a fancy way to write "per hundred" (/100). Of course, using your knowledge of place value, you know that 0.16 = sixteen hundredths = 16/100.

Realizing the meaning of the % sign, you can immediately write this as 16%.
