Required
Determine the number of tall buildings that had more than 60 floors
The histogram can be interpreted as follows:

More than 60 floors is represented with the following group: 61 - 80
The frequency of group 61 - 80 is 10
<em>Hence, 10 buildings had more than 60 floors</em>
Answer:
52.5
Step-by-step explanation:
You divide 35 by 10 and then multiply 15 by that number
9x + 8 = 2
Subtract 8 from both sides:
9x = -6
x = -6/9
Simplify:
x = -2/3
Points of intersection are (0,0),(0,8),(10,0),(4,6) plugging them into the equation you get 0,24,10,22. I don't know if you're looking for max value or min value.
