How many students had 3 or more absences? Add together {45%, 21%, 23%} and subtract that sum from 100%: 11%.
How many students had two or more absences? Add together this 11% and 21%: 32% had two or more absences. Let the total number of students be n. Then 32% of these n students add up to 96 students. Thus, 0.32n = 96, and n= 300.
How many students had one absence? The chart shows that that is 45%, and we know that there are 300 students total.
Thus, the number of students who had one absence was 0.45(300) = 135.
Prime numbers have only themselves and 1 as factors, like 7, and all other numbers are composite.
1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20
I attached the pictures with the work.
<em>x = 20</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>we have </em><u><em>opposite angles</em></u><em> =></em>
<em>2 + 3x = 62</em>
<em>3x = 62 - 2</em>
<em>3x = 60</em>
<em>x = 60 : 3</em>
<em>x = 20</em>
<em>Good luck !</em>
