First off, you can start with the 36 and 45. If 45 is 3/4 of 1 hour, divide it and 36 by 3. Now we have 15 minutes, (1/4 hour) and 12 miles. Lastly, to find mph, we can do *4 and we get 4/4 hours, (1 hour) and 48 miles.
(1) y=x-2
(2) y=x²-2
Then we deduce that x-2 = x²-2 ===> x²-x = 0 ==x(x-1) =0
so x = 0 or x =1. Plug these values in any of the equation to find y & you will find:
for x = 0, y = -2 & for x= -1 , y= -1

Original Question:
100 - [(25/5) x 10] = ?
Note: Always answer what's inside FIRST. In this case, the main ts the brackets, but there's also parenthesis in it too. So solve that.
→100 - [(5) x 10] = ?
Now, solve what's inside the brackets.
→100 - [50] = ?
Well, you can get rid of the brackets.
→100 - 50 = ?
Subtract!
→100 - 50 = 50
Solution:
50
