If you do 13.75-2.90 you're left with 10.85. Divide 3255 by 10.85 you get 300.
300 copies is your answer
This question is asking to find the answer of the variable x, and to do that, you need to isolate the variable, aka get it alone.
10x+2=32 (you must get rid of the 2 first, so do the opposite sign, so if positive, subtract the 2 from both sides.)
10x=30 (Divide 10 from x to get the answer.)
x=3!
Hope this helped you!
X is all of the following except a constant
The median is the middle of the list when the list is sorted.
6,10,11,13,14,14,20,20,23,23,26,27,31,33,38,38
This is the sorted list, so we count evenly up and down the list. In this case, there are 16 total numbers, meaning we count 8 up and 8 down, arriving at 20,23 with the middle being in between them. Both of them can't be the median, so we take the average of these two numbers, which is 21.5. So, the median 21.5.
Choice A is a trinomial, but it doesn't have a constant term
Choice D is the only other trinomial. This has a constant term, which is 6. The constant is the term without any variables attached to it.
Answer: Choice D
