Hi all!!!!!!!!!!!1
Please help me understand how to solve this inequality
2x > x + 10 > -x
here is what I did
subtract 10 from each side to get 2x - 10 > x > -x -10
subtract x from each side to get 2x - x -10 > x-x > -x -x -10
x-10 > 0 > -2x -10
then x-10 >0 leading to x> 10
also 0 > -2x - 10 then im stuck. does my attempt at a solution make any sense at all?
thanks so much it all makes so much sense now. I appreciate your explanation
This is what i have done. how much mary paints in an hr=1/4. how much john paints in an hr=1/6. If the total time it takes for both is X hours, then Mary takes X/4 and John X/6. Now, together---- X/4 + X/6. form an equation 1=X/4 + X/6
1=3X +2X
--------
12
12=5x, x=12/5, x =2.4 hrs. in minutes 4/5hrs =4/5 * 60 =24 minutes
so time its takes to do it together is 2hrs and 24 minutes.
this is the correct answer according to my answer sheet but I honestly cant seem to really realy understand the concepts here. Can some one please enligten me and let me know if my reasoning here is right. thanks
Mary can paint a house in 4 hours. John can paint same house in 6 hours. How long will it take them to paint the house if they are woking totogether?
Thanks
