Show that 43n plus 83x923n-1 is divisible by 7 for all positive integers n I know that you have to use modulo 7 in this question if you use it please explain why. please use very simple terms?

Perhaps (yes, perhaps... I may be At Fault here) your intended question is slightly different from the way you wrote it. Since I don't know exactly what that question is, I will answer the question that you wrote.
43n + (83)(923n)-1=43n+76609n-1=76652n-1.
Say that n=1. Then you have 76652(1)-1=76652-1=76651.
76651 is not divisible by 7, so I have contradicted your postulate.

Do whole numbers include all positive integers?
The answer to the question depends on what property of positive numbers the question is about.If your question is a case of adding random apostrophes, then the answer is yes, they do include oll positive integers. - No apostrophe required.
What is the smallest positive integer that is divisible by all of the integers?
Your question doesn't make sense, I'm sorry. Integer means a natural number like 2 or 10 or 1047893671282 or even -1048278163.
How do you find the integers of a number?
That question does not make sense An integer is any whole number (can be positive or negative)
a collection of positive integers?
Positive integers would be 1 - infinity. Such as 4, 836, 2, 15, 9999999903674657, 167, 88, 56, 4586, and any other number that is positive and does not include a decimal point. Example: -5, 10.5, -76.6 can not be used as a positive integer.I hope I answered your question. Thank you for asking.
How do you divide integers with the same sign?
When dividing integers with the same sign, your answer will be positive. 10 divided by 2 is 5. -100 divided by -50 is 2. I hope I answered your question. Thank you for asking.
Why is the product of any consecutive integers divisible by 6?
There must be three consecutive integers to guarantee that the product will be divisible by 6. For the "Product of three consecutive integers..." see the Related Question below.

What is a positive number between 1 and 10 chosen at random is composite?
The answer to the question is 0 since there are infinitely many positive irrational numbers between 1 and 10.Assuming you meant positive integers, the answer is 4/8 = 1/2.The answer to the question is 0 since there are infinitely many positive irrational numbers between 1 and 10.Assuming you meant positive integers, the answer is 4/8 = 1/2.The answer to the question is 0 since there are infinitely many positive irrational numbers between 1 and 10.Assuming you meant positive integers, the answer is 4/8 = 1/2.The answer to the question is 0 since there are infinitely many positive irrational numbers between 1 and 10.Assuming you meant positive integers, the answer is 4/8 = 1/2.
How are integer are different from natural no?
Integers can be both negative and positive but natural numbers can only be positive...hope that answers your question... :D
Explain why the sum of three consecutive integers is divisible by three?
Here are some consecutive odd integers. All must follow this form: x+x+2+x+2=3x + 6 6 is divisible by 3. So is 3x. If you add two integers that are divisible by 3, it is still divisible by three. The question is not about odd integers, but consecutive integers. This should be x + x+1 + x+2 =3x+3 A bit simpler would be the three in a row : x-1, x, x+1 which add up to 3x which can be divided by 3.
The sum of two consecutive positive even integers is at most 16 What are the integers?
Question doesn't make sence, but I would say that answer is 8 + 8 = 16

What is a set of numbers that includes 1 but not zero?
The set of positive integers contains 1 but not zero. Within the set of integers, there is the subset of positive integers, the subset of negative integers and the subset with a single element in it - zero. There are a zillion other sets that could be specified that meet the conditions set down in the question. The one cited is an easy one.

Are all numbers that are divisible by 5 also divisible by 10?
Well, not technically. You cannot divide 5 by 10 (if you want a positive number that isn't a decimal.) But, ALL NUMBERS THAT ARE DIVISIBLE BY 10 ARE DIVISIBLE BY 5! You just have to turn that question around.
Is 3.5 is an odd number?
Because it is not divisible by 2 with no remainder
