28 x x x ... x x 34 Let's use 13 numbers. So, the 7th is 30 28 x x x x x 30 x x x x x 34 If we want integers, there aren't that many between 30 and 34, so some will have to be used at least twice. Let's make the mode (29) occur 4 times: 28 28 29 29 29 29 30 31 31 32 32 33 34

I need help solving this problem, I have followed the sequence forward and backwards but can't seem to find the solution. I believe it's the pigeon hole theorem. Here's the problem; Let A be any set of twenty integers chosen from the arithmetic progression 1, 4, 7, ...,100. ...

If a and b are positive integers and their product is 3 times their sum, what is the value of 1/a + 1/b? Given that ab = 3(a + b). From this, ab/3 = a + b. Dividing through by ab yields 1/a + 1/b = 1/3.

a. Show that in any set of n integers, there is a subset whose sum is divisible by n. b. Show that for any integer n, there is an integer whos digits (in decimal representation) consist of only 0 and 1. I dont think the first can be proved. However, in a set of 2n-1 integers, ...

Maths (V. Hard)
Firstly calculate how many Pythagorean Triples there are that have no component larger than 300. Next find the sum of all the Hypotenuses from these triples you found in step 1. Finally add together the results that you recieved in the first two steps and you'll receive the ...

Hey guys! I need help with this problem..it tells me to write a number line to tell the answer..the question is : What is the smallest integer greater than -2.1? Is it to -2 right? I have no idea. I forgot all this back in elementary T_T. Yes. Negative integers are also ...

Fractions and Integers
If x/4+y/5=19/20 where x and y are positive integers then x+y is? If you multiply through by 20 then you'll have 5x+4y=19 where x and y are positivie integers. Can you solve that? Hint: you only need to look at the integers less than 4. Thanx a lot.

how do you solve integers? There are about a thousand different types of problems with integers, so it depends on what type of problem. Do you have something specific in mind? In general, modulo arithmetic is used, but it is taught in very few schools these days. Sometimes ...

When you add integers, why do you subtract? -9+5=-4. I do not understand why there is an addition sign. How do you know when you are suppose to subtract.

If x and y are positive integers and x/5 + y/8 = 17/20, what is the value of x + y?
Monday, September 16, 2013 at 4:15pm by Alice
x/5 + y/8 = 17/20 multiply by 40 8x + 5y = 34 y = (34-8x)/5 Since my numbers must be positive integers, 34-8x must be a multiply of 5 and furthermore x can only be 1,2,3, or 4 So we only have 4 numbers to try if x=1 , y = 26/5 , no good if x = 2, y = 18/5 , no good if x = 3, y...
