Answer:
Step-by-step explanation:
The wording "fewer than" is translated to the math symbol "less than". The variable n represents the number of students.
<em>the number of students</em> is fewer than 18
translates to ...
n < 18
__
The wording "at least" translates to the math symbol "greater than or equal to."
<em>the number of students</em> is at least 15
translates to ...
n ≥ 15
The cost of each pen is $50, because you spend $600 on books leaving $200 to buy FOUR pens, making it $50 per pen
So, this is asking for any number that subtracts to = 16-7
Well, 16-7= 9 so use any two numbers that would subtract to equal 9
Like so:
11-2=9
18-9=9
34-25=9
-2-11=9
Etc....
Hope this helps! :)
It is most likely looking for a simplified version of the answer
Based off that assumption it would be
9:7
It shows that six years pasted between 2007 and 2013 and it increased by 20,000 so add that to the population at the time the answer is 158000
