This is a lowest common multiple question.
to find the lowest common multiple, you need to find the prime factors of the two numbers:


Take out duplicates:

and multiply them together:

and that is your answer.
Easy peasy.
Answer:

Step-by-step explanation:
Let t represent the number of teachers.
We have been given that Noor gave 1/3 of a sheet to each of the 45 students at recess.
Let us find the number of sheets given to students by Noor by multiplying the total number of students by the part of sheet given to each student.


So, Noor gave 15 sheets to 45 students.
We have been given that Noor wants to give
sheet to each teachers, so the number of sheets given to t teachers will be
.
As Noor has bought 21 sheets, so the number of sheets given to students and t teachers will be less than or equal to 21.
We can represent this information in an inequality as:

Therefore, the inequality
represents the number of teachers ,t, Noor could give sheets of stickers too.
Answer:
I only know one way and its x = 7
Step-by-step explanation:
20 = 5( x -3 )
20/5 = x- 3
4 = x - 3
4 + 3 = x
7 = x
Solving the quadratic function, it is found that the range is of:
between 200 and 250; inclusive
The profit for x tours is modeled by the following equation:

It is concave down, so the monthly profit will be of at least $60,000 between the two roots when
. Thus:


Simplifying by 2:

Which has 
Then:

At least $60,000 includes $60,000, thus the interval is inclusive, and the correct option is:
between 200 and 250; inclusive
