Creating a System of Linear Equations

we can set the costs of armchair by $x$ the sofa bed by $y$ and the double beds by $z$ so we get the system $20x16y12z=19600$ $15x12y9z=15700$ $12x10y6z=11600$

1. help squeezing an armchair through a narrow corridor, please help?

See if you can remove the legs to make it narrower to fit the hall

2. What is the difference between a theoretical physicist and an armchair physicist?

An armchair physicist is useless. They are usually the ones who say amusing things like: "Look, I do not need to understand math, just argue the concepts!""You need to be more open-minded about the aether.""Nobody understands quantum mechanics."etc.

3. Two fainting spells in three weeks: Armchair physicians, tell me why?

I have low blood pressure and I faint easily. I am also extremely thin. I have something called...mitral valve prolaps? I took martial arts classes with the two top heart surgeons in my city and they diagnosed it right in class. They said it was common in very thin people. Always best to ask doctor if you can. Did your father tell them that you had previous fainting spells?

4. Any armchair theories on why the island on "Lost" is so?

Hey North, I believe that it is a parallel of our own lives. The "Others" - We do not trust people that are not like us! When we have an issue like immigration or Gays wanting to get married or prayer in the schools - WE GET VERY HOSTILE! The "Island" - There is no person to save them. No government, No mom, No family - It's up to them and their own wits. What would happen if you were one of those people in hurricane Katrina or in the Tsunami in Indonesia at Christmas? Who would be there for you? The "Plot" - What will happen to all of them? What would happen to all of us? We have turmoil in the Middle East, Problems with Iran, Oil producing countries that have a strangle-hold on all of us.... What will they do? Just my thoughts, James in San Diego

5. Real Military people (not the fake armchair warriors posting in this section)?

In WW2 i would have been busy shooting at the people (im german) who served under him... So the answer is no ;)

6. Does India have an excess of armchair experts?

Yes and No.Yes becauseIndia is a nation of 1.2 billion plus people. We have an excess of everything, well almost everything. Not too many Olympic medal winners, for instance. In the privacy of our living rooms or in the company of friends in tea-houses we have always opined - on trivial issues and on issues of great import. No wonder Amartya Sen wrote about the Argumentative Indian. Social media has made expressing your opinion that much easier and we are just taking advantage. The culture has always been such that it has encouraged an individual to have an opinion. At least that was the case in the past. You will remember the Mahabharat has many instances where youngsters were asked their opinions, always before the elders so that they did not feel stifled or obliged to repeat what an elder had said. Sadly, the present curriculum and teaching methods and family life does not encourage independent thought but goes the other extreme and prevents it in most cases. Access to the internet is not helping the least - you do not really need to make up your mind, you can read up what others are saying and use it convincingly in most cases. No becauseWe also have a lot of genuine experts and doers - again that population thingie. They have contributed a lot to society and addressing issues. Quite a few have actually succeeded against all odds. IMO this is not unique to India - happens across the world. There are more 'armchair experts' than 'experts' / would oers' any day. Just that our numbers and access to media makes us loud. In any case loudness is a very Indian characteristic.Confession: I too am an armchair expert on a number of issues. What to do? We are like that only!

7. Are armchair critics running the Iraq War based on media reports?

I am not sure that most people within the military who are in policy making positions watch the news. Occasionally to follow a story they might but most of the policy makers read the news from the wall street journal or Washington times from my experience. There is a publication created from news stories called the "Early Bird" which is circulated around to allow people to get the news without all the other crap thrown in. Having said that - I think the problem most of the leadership is having in Iraq specifically is the "Wishful thinking syndrome" they believe something to be the case and make decisions to further that outcome. The American people for the most part have stopped watching the news on tv. Look at the statistics in viewership drop since the conflict began in 2003 - most national news networks have lost up to 20% of "regular viewers". This is due to the shift to reporting the hour by hour stuff rather than a news overview and having specific news stories get more depth. Currently the average American is getting his/her news from the internet and unfortunately quite a few of them are using blogs to get it. I also submit for consideration that the "average middle class" American still wants everyone in the world to live at his standard of living and would support intervention to help spread this process. It has become appallingly obvious that our technology has exceeded our humanity. - Albert Einstein
