X>43/3
Or X>29/3
Depending if you mean (7-2)/3 or 7-(2/3)
Replace,
x = y
Or
x = f(x)
then us stay:
x = 5y + 12
Isolate 5y
5y = x - 12
Dividing both the sides by 5
y = x/5 - 12/5
Then, replace y = f^-(x)
f^-(x) = x/5 - 12/5
Hope this helps
2,500,000/365 = 6849 per day.
6849/24 = 285 per hour.
285/60 = 4.75 which is rounded to 5.
So 5 per minute
Hope this helps!

i would suggest memorizing this
hence
The distance is 3, because 7 - 4 = 3.
