1/5+1/7=12/35 of one room painted per hour
1 room/(12/35)=35/12 hours per room working together

Multiply $39.79 by 8.25% (.825) = $3.28
Then add $3.28 to $39.79 = $43.07
Hmm, we will do ratio and assume caputred is in proprtion
so
all:tagged=all:41
we will assume this is the same as
57:tagged in the 57
57-41=16 so 16 are not tagged
so
all/41=57/16
times both sides by 41
all=2337/16
all=146.something
about 146 storks
5. 5x-5
. ------------------
. 10x²-25x+15
We can first factor 10x²-25x+15, it will turn into (2x-3) and (5x-5)
(if you need help on factoring, please leave a comment)
So the question will be like:
. 5x-5
. ---------------
. (2x-3)(5x-5) The factored answer is the same as the original . number, so the factor answer can replace it.
We know 5x-5 on the top and 5x-5 on the bottom is the same, so they can cancel out, and it will become:
2x-3=0
Then solve
2x-3=0
2x=3
x=2/3
