haha :) Hold on please
put the question in the question section though plz - edit the ?
Jean and Mark are going to fill a pool with 2 different sized hoses. Jean can fill the pool in 8 hours, while Mark can complete it in 12 hours. Their supervisor thinks that the job will take 10 hours to complete if they work together. Explain each step in solving this equation, and determine if the supervisor is correct or not.
The "edit question" isn't working. I typed my question but it won't let me submit it.
so jean fills 1/8 of the pool per hour. do u understand that?
ok. so then for mark.
Find rate of filling for each person Jean fills pool on 8 hrs IN hour she fills 1/8 of the pool Mark fills 1/12 in 1 hour together let them they take x hours so we have 1/8 + 1/12 = 1/x Solve for x
does that help? ^^^^^^^^^^^^^^^^^^^^^^^
yes. So the LCM would be 24x?
So I multiply each fraction by that correct?
alright, hold on
youre doing great!
3x/24x + 2x/24x =24/24x
what do I do now?
@Kash_TheSmartGuy @Jhannybean @freckles
well each fraction has a denominator of 24x yes thats right
So what would be the answer?
divide both sides by 5 to get x = ?
24 / 5 = 0.208????
yea that's it 4 .8 hours
So then the guy would be wrong, right?
