Best ResponseYou've already chosen the best response.1i think you made a mistake there q+122(q22)>0 q+122q+44 >0 q +56 >0 q > 56 q>56

Best ResponseYou've already chosen the best response.0I agree with jayz657's work. Any questions, @cbm ?

Best ResponseYou've already chosen the best response.0Thank ya'll so much! I was reworking it. Yep, once I distributed I got the same answer. The sign at the end changed right? From > to <

Best ResponseYou've already chosen the best response.0I wish you could give more than one best response

theEric

Best ResponseYou've already chosen the best response.0Yep! Because you multiplied or divided by a negative!

Best ResponseYou've already chosen the best response.0My pleasure. I'm glad you got it worked out :) Good luck with any more you have to do!

Best ResponseYou've already chosen the best response.0Thanks, I'm struggling with one more now trying to set up an inequality.

theEric

Best ResponseYou've already chosen the best response.0You can ask it here or in another question. I have time if you'd like a hand. Algebra like this can be hard at first.

Best ResponseYou've already chosen the best response.0Ok, it will take me a minute to type it. Thanks for your help. Yes, I'm too old to learn this stuff.

Best ResponseYou've already chosen the best response.0Haha, no such thing. It might just require some thinking and rethinking, right? Maybe thinking in a different light! I started thinking about counting cookies/blocks again before so the numbers meant something.

Best ResponseYou've already chosen the best response.0Your making a rectangular patio that is 10ft wide and 20ft long, using square pavers that have an area of 0.81 sq ft, what is the # of pavers u will need? Write and solve an inequality to find the answer.

cbm

Best ResponseYou've already chosen the best response.0Lol, I'm trying. I thought I had equations but not the fractions

cbm

Best ResponseYou've already chosen the best response.0would it be like (10x20).81=p

theEric

Best ResponseYou've already chosen the best response.0The first step is always understanding the problem. Then we move on.. So I have a quick question... Each "paver" is .81 square feet, and we need to know how many of the will fit in our 10 foot by 20 foot area?

theEric

Best ResponseYou've already chosen the best response.0Alright! Then (10*20) is definately your area of the patio. And you wanna see how many .81 area portions will fit into that. How many times does .81 go into (10*20) is the question to get you to your answer. That's a division thing.

theEric

Best ResponseYou've already chosen the best response.0That's just one way to look at it. There's another way in which you build the equation and solve.. I got the same number after rounding. Is this supposed to be inequality?

cbm

Best ResponseYou've already chosen the best response.0I'm not sure if I'm writing the inequality right or not (10ftx20ft)/.81=p

cbm

Best ResponseYou've already chosen the best response.0Yes, it's supposed to be an inequality

theEric

Best ResponseYou've already chosen the best response.0That's what I would do to!

cbm

Best ResponseYou've already chosen the best response.0To me it works and gives the answer when you work it.

theEric

Best ResponseYou've already chosen the best response.0I don't see why it would be inequality! There must be something I'm not thinking of.. I thought it would want an exact number...You want so many pavers.... OR! Do you want at least so many pavers? Meaning that many or more?

cbm

Best ResponseYou've already chosen the best response.0Do you want me to create a problem so I can give you a medal? I'm not sure what the medal do.

cbm

Best ResponseYou've already chosen the best response.0I was trying to figure out why it want come out to a whole number also unless it's ≥

theEric

Best ResponseYou've already chosen the best response.0They're just sort of recognition you can count. I'm not worried about it. Thanks though!

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0Yeah, I think maybe that's the idea of it.. why they want inequality.. Although you'd think rounding it up to 247 would be good enough! Maybe the question was just not appropriate for this subject!

cbm

Best ResponseYou've already chosen the best response.0Oh, ok thanks! Maybe (10x20)/.81≥p

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0I would say \[p\ge 246.0\]

theEric

Best ResponseYou've already chosen the best response.0You would want more pavers rather than less. At least you get your patio done that way :P

theEric

Best ResponseYou've already chosen the best response.0Pavers area things should be greater than or equal to the patio area... to get the patio done :P Yeah!

theEric

Best ResponseYou've already chosen the best response.0Using just that sentence, you can set up the inequality. \[p_{NumberOfPavers}\ge A_{PatioArea}\]

Best ResponseYou've already chosen the best response.0I've been trying everything to get an even number. I don't understand why it would be a decimal. I tried breaking it up into inches, etc. Thanks again for your help.

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0It might just not come out to be an even number. It happens. We could solve it to be a fraction instead of a decimal. With fractions, your always exact (no rounding).

theEric

Best ResponseYou've already chosen the best response.0I have five cookies to share between us. How many can we each have? 2.5. Books don't always make problems come out to nice numbers either..

theEric

Best ResponseYou've already chosen the best response.0So maybe that's the case here.

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0Same. Good luck with that! If you solve it as a fraction, note that .81 = 81/100.

theEric

Best ResponseYou've already chosen the best response.0\[\frac{10*20}{.81}=\frac{10*20}{\frac{81}{100}}\] Np!

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0Just in case... From there, it's \[\frac{10*20*100}{81}=\frac{20000}{81}=246\frac{74}{81}\]

cbm

Best ResponseYou've already chosen the best response.0Yep, that works good or at least it looks better. I figured I could write the equation as (p)x0.81≥200. I'm still working it to see if it will work.

theEric
 2 years ago
Best ResponseYou've already chosen the best response.0That's great, and it was the other way I would think of the equation to solve!

theEric

Best ResponseYou've already chosen the best response.0And you don't have to change the sign because 0.81 is not negative.dw:1351404148861:dw

theEric

Best ResponseYou've already chosen the best response.0All other operations keep the inequality the same direction. Adding (positive number) to both sides: Each side gets the same bump up Subtracting (positive number) from bothe sides: Each side gets the same cut down Multiplying (number greater than 1) to both sides: Each side gets larger proportional to its size Dividing both sides by (number greater than one): Each side gets smaller proportional to its size

theEric

Best ResponseYou've already chosen the best response.0I threw in number specifications, just because adding a negative is like subtracting a positve. Then each side gets cut down the same. Same for multiplication/division. Multiplying by a fraction less than one is like dividing by that fraction's reciprocal\[x*\frac{1}{2}=x\div 2\]and so each side gets proportionally smaller. Just some extra, if you wanna think about it. Take care! It was nice working with you!
