Answer:
72%
Step-by-step explanation:
Start by turning both percentages into decimals. To do this take the percent and divide it by 100. So, 60% = 60/100 or .6 and 80% = 80/100 or .8.
Next the student has already completed 20 quizzes. So, 50-20=30 remaining quizzes.
Quizzes already taken:
= 12 passed quizzes.
The remaining quizzes for the school year:
= 24 quizzes
So, Finally add them both together and divide by the total amount of quizzes:
12+24
= 36 passed quizzes
=.72
Now to convert it back into a fraction you multiply the decimal by 100.
= 72%

The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.
