I believe you would take 127.5 and divide it by 8.5, try that and see if that works, hope this helps!
The set is not closed
Example:
-4 * -3 = 12 this is not a negative integer
I think that C and D are the correct answers
Constant of Proportionality = d/t = 90/2 = 45 mph
In short, Constant of Proportionality would be: 45 miles per hour.
Here, d/t = 45
d = 45t
In short, Your Equation would be: d= 45t
Hope this helps!
