To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:
10:33
-
7:18
Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies.
5/8+ 2/5
= 25/40+ 16/40
= 41/40
= 1 1/40
The final answer is 1 1/40~
3x=8
Solve for x by dividing by 3 on both sides
x=8/3
Now plug 8/3 in for x in second equation
3(8/3)+y=15
This gives you
8+y=15
Subtract by 8 on both sides to find y
y=8
Now write it in ordered pair form (x,y)
So your answer is (8/3,8)
Log ( base 2 ) ( 1 / 4 ) =
= log ( base 2 ) ( 2 ^(-2 ) ) =
= - 2 log ( base 2 ) 2 = ( because : log x^n = n log x )
= ( - 2 ) * 1 = ( because: log (base x) x = 1 )
= - 2
