E n is an even-number function Find E9 when En equals 2n?
If n = 9 then 2n must be 18.
What is difference between the n and 2n number?
2n is 2 times n.
How do you get 9 from 2n plus 4?
'n' can be any number, but when applied to (2n + 4), n = 2.5
What are the consecutive even number?
They are numbers of the form 2n and 2n+2 where n is any integer.
What is a number if the difference between five and twice the number is one?
5 - 2n = 1 4 = 2n n = 2
E n is an even-number function Find E9 when En equals 2n?
If n = 9 then 2n must be 18.
A sum of a number and twice its number?
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
Twice what number is equal to three times that number?
let the number be n. Then: 2n = 3n ⇒ 2n - 2n = 3n - 2n ⇒ 0 = n ie, the number is zero.
What is difference between the n and 2n number?
2n is 2 times n.
Is 2n a whole number?
The answer depends on n. If n is an integer or half on integer then 2n is a whole number; if not, then it isn't.
How do you get 9 from 2n plus 4?
'n' can be any number, but when applied to (2n + 4), n = 2.5
What is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers?
Let the first odd number be 2n-5 (n ≥ 3), then the 6 consecutive odd numbers are: 2n-5, 2n-3, 2n-1, 2n+1, 2n+3, 2n+5 And their sum is: 2n-5 + 2n-3 + 2n-1 + 2n+1 + 2n+3 + 2n+5 = 12n The greatest common factor for all n(≥ 3) of 12n is 12. Thus 12 is the greatest whole number that MUST be a factor of the sum of any six consecutive positive odd numbers.
Five less than twice a number is 7?
If the number is N then 2N - 5 = 7 then 2N = 12 so that N = 6
What expression represents twice a number n plus three?
twice a number n is 2n plus 3 is + 3 → twice a number n plus 3 is 2n + 3.
What does the term 2N mean?
2n is the diploid number. It double the number of chromosomes present in a genome. 2n represents the number of chromosomes in a somatic cell. The number n is called the haploid number. n represents the number of chromosomes present in a germ cell
2n to n?
The relationship 2n to n means that one set has double the elements of the other set. For example, if n=3, then 2n=6, indicating that there are twice as many elements in 2n as in n.
Find three consecutive integers such that the sum of the first twice the second and three times the third is 86?
n + 2(n+1) + 3(n+2) = 86 n + 2n + 2 + 3n + 6 = 86 6n = 86 - 2 - 6 6n = 78 n = 13 Three consecutive integers are = 13,14,15
