13. y > 2
14. x - 13 < 9;; x < 22 
15. x + 86 < 263;; at most 177 pounds
 
        
             
        
        
        
Answer:
3 and 8/10
Step-by-step explanation:
38/10=3.8 you can have three groups of 10 and 8/10 of another group
 
        
             
        
        
        
We have sequence equation  .
.
In this case n is a natural number (1, 2, 3, ...).
So start inserting and computing value of  given that you know the value of n and a.
 given that you know the value of n and a.

Well, let's look at the answer choices.
A) If you want to fond the total cost of two sweaters you would add, not divide. So this isn't it. 
B) To find out how much older someone is you would subtract. So this isn't it either. 
C) To find out how many desks are needed you would multiply, since you know you need 3 rows of desks with 7 students each (3 x 7). Again, not it.
D) To find out how many pencils each student would get, you'd divide. You would divide 56 by 9. So your answer is D.
        
                    
             
        
        
        
Answer:
1
Step-by-step explanation:
Hi!
First we need to translate 2 units down. That means we need to subtract 2 from the y value. So now we have (-1,1).
For a 270 degree counterclockwise rotation the rule is to go from (x,y) to (y,-x)
So now we have (1,1). Since they're only asking for the x value, the answer is 1.
