Verdich [7]2 years ago
4 0

Answer:  C   2x(x - 2) - x = 0

 and <u>B</u>   2x² – 5x=0

Step-by-step explanation:

You get 2x(x - 2) - x = 0 by subtracting x from both sides of the original equation.

Then take 2x(x - 2) - x = 0 and distribute to get 2x² - 4x -x = 0

combine the x terma and you end up with 2x² – 5x=0

Will give brainliest and 5 stars
BaLLatris [955]
First, find what percentage of students had 3 or more by adding up your known percents:

45% + 23 % + 21% + x% = 100%
x = 11%

Since you're given that 96 students had 2 or more, you add up the percentages of 2 and 3 or more:

11 + 21 = 32%

Now set up a proportion that relates it to the whole:

\frac{96 students}{32 percent} = \frac{x students}{100 percent}

This will allow you to find the total number of students at the school.

Cross multiplying and solving for x results in 300 total students.

Question 1:
45% had one or more absences. 45% of 300 students is 135 students.

Question 2:
As we found before, 11% of students had three or more. 11% of 300 is 33 students.
