Answer:
and 
Step-by-step explanation:
we have

we know that
Compound inequality can be divided into two inequalities
so

rewrite

and

therefore
An equivalent form of the compound inequality is
and 
You would take the square root of x^2 and of 121 so x =11
The answer would be 12 students. 8+4+6+3=21.
84 divided by 21 would = 4.
3 students times 4 = 12 students
A:40%
If you put 60 over 150 and x(percent of students) over 100 and cross multiply 100 and 60, you will get 6000. You then divide that by 150 which leaves you with 40 as x and 40 over 100 is 40%.
Answer: The correct order is D.
