Answer:

Step-by-step explanation:
Let x = number of books that Hannah donated
We know that the number of students is 150 and the total number of books is represented by b, we can write that as:
Average number of books donated by each student = 
Now we know that Hannah donated 3 times as much as the average. We can write that as:

4x - 7 < 17
+ 7 + 7
4x < 24
4 4
x < 6
Solution Set: (6, ∞) and {x|x < 6}
Answer:
Option C is correct
$528 will the total cost spends by coffee shop
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates.
As per the statement:
A coffee shop spends $408 for an order of 17 cases of paper cups.
Unit rate per cases = 
Now, if If the coffee shop adds 5 more cases of paper cups to the order

To find how much total cost coffee shop spends.
Total cost = unit rate
total number of cases
= 
Therefore, total costs coffee shop spends = $528
Answer:
(10,10)
Step-by-step explanation:
coordinates are (x,y)
x is horizontal(left and right), y is vertical (up and down)
going down 6 means subtracting 6 from the second number
lets reverse that to go up and add 6 back
4+6=10
so the original point was (10,10)
