Answer:
x = (4y-6)/17
where x is the number of pens each student got.
Step-by-step explanation:
No. of boxes = 4
no. of pen in 1 box = y
total no, of pens in 4 box = No. of boxes *no. of pen in 1 box = 4y
No. of pen took away by Jaden's teacher = 6
no. of pens left = 4y - 6
This, 4y - 6 pen has to be divided among 17 students.
Let each student get x pen
thus, total no. of pen got by 17 student = 17x
This, 17x should be equal to total no. of pens available which is 4y-6
17x = 4y-6
=> x = (4y-6)/17
Thus, expression to represent number of pens each student got
is x = (4y-6)/17
Solve x(x-5)=0; the roots are 0 and 5.
Draw a number line. Plot 0 and 5 on this line.
Set up 3 intervals, as follows: (-infinity, 0), (0, 5), and (5, infinity).
Now choose a test number from within each interval (e. g., -2, 3, 10).
Subst. each into the inequality x(x-5)

0. In each case, determine whether the inequality is true or false.
Based upon your results here, you should be able to determine on which interval or intervals the inequality is true. Those interval(s) is/are your solution set.
Answer: About 12 of those 60 students are boys.
To find the percent, you'll convert 20% to a decimal.
20 / 100 = 0.2
Then, multiply 60 by 0.2
0.2 × 20 = 12
That's one way, another way is:
Convert 20% to a fraction.
20% = 1/5
Then multiply 60 by 1/5.
60 × 1/5 = 60/5
Lastly, divide 60 by 5
60 / 5 = 12.
Hence, 12 is the answer.
