Another question: If the expression 12x represents the ticket sales for a one-day concert in a stadium that holds 7525 people, does it make sense to say that x can be any number? Explain.

the value of the expression increases.\n\nUmm don't think so cuz negative numbers are real numbers and a negative number wouldnt make sense.

The following is a cogent edit of the paragraph in question, though I have taken liberties with it, the meaning is the same:\n\n"All the XBOX's were securely packaged prior to their delivery.  The 27 sets of XBOX's in case no. 3 must have been damaged during transportation.  We will take immediate steps to reimburse the buyer."

That's an extremely good question. \n\nThe answer is simple. Before that, i will explain what your question means to those who don't get. Well, it means that we must get 24 using 1,3,4 and 6 any number of times however involving operations +,-,* and / only once. \n\n  Then, the answer is very simple :\n\n  {[(6*6)/(3-1)]+[6]}  =  24\n\n---------------------------------------------------------\nWOKRING :\n\n {[(6*6)/(3-1)]+[6]}   =  {[(36)/(2)]+[6]}\n                       =  18 + 6\n                       =  24\n\n----------------------------------------------------------\n\nI hope you post more questions like these. They evoke a lot of thought. I hope the solution serves th purpose.

You put a round bracket "()" on the number line when the sequence doesn't include the number where that bracket goes. For example, if the final answer you get is "all the numbers between 2 and 8, excluding 2 and 8" then you use the round brackets. You'll know your answer excludes a number or numbers because it will be "bigger than" or "smaller than" only, not "bigger than or equal to" or "smaller than or equal to", in other words, ther will be no line underneath the inequality sign. \nNow, if you do get something like "x is bigger than or equal to  8 and smaller than or equal to 2" than you know your answer includes 2 and 8, so you use the brick bracket, "[ ]". Good luck.

let x equal the number of student tickets and y nonstudents\nx-250=y because 250 fewer nonstrudent tix were sold\n6x+9y=10500 because of tix prices\nsubstitute\n6x+9(x-250)=10500\n6x+9x-2250=10500\n15x=8250\nx=550 student tix\ny=300 nonstudent tix

Let s = number of student tickets.  Then 50-s = number od adult tickets.\n\n2s + 7(50-s) = 250\n\n2s + 350 - 7s = 250\n\n-5s + 350 = 250\n\n-5s = -100\n\ns = 20\n\nso 20 student and 30 adult\n\ncheck: 20X2 + 30X7 = 40 + 210 = 250 check

1,000,006 is correct for one million six. If it is one million AND 6 then it would be 1,000,000.06. Notice the point. The word "and" is where the point goes.

These numbers seem to be defined as : x,x+2,x+3 for every triplet. \nTherefore, 1,3,4,5,7,8,9,11,12,13,15,16,...

They are better when finding answers to a question with possibly more than one right answer. For example, solve for x: 5x=15 would be best with an equation because it's easily solvable with one answer. Whereas, A number greater than 9 but less than 12 would be set up as 9<x<12 or 9<x & x<12.  This way, x could be any number between 9 and 12, having infinate solutions. If you have to see how much money you can spend with out going over the allotted amount, would be a real world situation. (IE- You have 20 dollars to spend, and you can't spend negative dollars, so 0<x<20). There you go!

It means that the value of the function f at x is an element of the set containing only the number 3, so f(x)=3.\n\nFor example, if it was R+ instead of {3} with an additional statement "for all x in R" then it would mean that the function only takes on non-negative values for all real numbers.

I never understand how x can stand for Christ. It make no sense. It is not like 2 for to,too,two or 4 for for,four.

Ok, your question makes absolutely no sense.  Why say we can only use 1 through 16, and then say we can only use 1?\nSome ways, assuming I translated your question correctly, would include 16 + 16 +1 +1, and 16 + 15 + 3.... There are almost an infinite number of ways to add to 34 with the numbers 1-16, so please rephrase your question.

Interesting to think about.  I don't agree with the people who said 1+1 is not 3.  While I agree with that statement, I don't agree with that as to being the answer.  You're wanting to know if it is right... and your showing that you are making 1+1 equal 3 by turning it into 1.5 thru mathematical equation.  I need to think about it........no, It can't be.  Because at one point you change x+x= 3 into 2x=3. If x equals 1 then at first you have 1+1=3 then you change it into 2(1)=3  Which means 2•1=3 when it does in fact equal two. When a number and a variable are next to each other, it means they are multiplying.  And in this equation, x=1 so 2x=3 is not correct.  But I like the thought.  Darn, and here I thought I'd just read something that changed the laws of physics and mathematics.

by inspection I can understand another point will be...\n\n(0, 5) because if you add 1 to X you must add 2 to Y

I'm not sure if the x is supposed to be the multiplication symbol or a variable.\n\nIf you mean 2*(4*2) or 2(4*2), the result is: 16\n\nIf it is the letter "x", the answer is:\n2x(4*2) = 2x(8) = 16x

Here's what you should think: 3 times a number that has to be zero or higher, then having another 3 added to it, cannot possibly equal 1 (it must be at least 3).  So there is no solution.\n\nYou did say it was an inequality, though.  If the = was really > or >=, the answer is all real numbers.  If it was < or <= the answer is the empty set.
