What does n over 12 equals 20 over 30 Please help?
If n is the variable then it's making the two sides equal to one another. So the question is what is n, if n/12 = 20/30 ? First of all 20/30 is 2/3 when that fraction is reduced. Once you have n/12 = 2/3 ... isolate the n, in the equation so... n = (2/3) x 12 .... therefore n = 8. We can prove this by substituting 8 to n .... 8/12 is equivalent to 2/3 whereas 20/30 is equivalent to 2/3. Thus 2/3 = 2/3.
What is n in this equation 2 plus n-3 equals 6?
2+n-3 = 6 n = 6+3-2 n= 7
If n plus 2 times 3 equals 21 what is n?
n + (2 x 3) = 21 Therefore, n = 21 - (2 x 3) n = 15
What is 3n plus 3 equals n plus 7?
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
What is 20 equals 5 plus n over 3?
20 = 5 + n/3 15 = n/3 n = 45
What is the value of n in the equation 2 over 3 times n equals 4 over 9?
The question is ambiguous. Does "2 over 3 times n" mean 2/(3*n) or (2/3)*n
What is the answer to 2 over 16 equals n over 3?
n = 3/8
What is n over 2 plus 5 equal 3?
n ___ = 3 2+5 n = 3(2+5) n = 3(7) n = 21
What are the next 3 terms in the sequence 2 over 1 and 3 over 2 and 4 over 3 and 5 over 4 showing a rule for the nth term?
If you mean 2/1 3/2 4/3 5/4 then the next 3 terms are 6/5 7/6 8/7 and the nth term is (n+1)/n
What is the answer to negative three equals negative five plus n over 3?
2=n
Is 1 over 5 greater than 2 over 3?
N. O. No.
When you divide the number by 5 there are 3 left over and when you divide the number by 8 there are 2 left over?

Multiple by 8 without using multiplication or addition Now do the same with 7?
Let n = the number multiplying by For 8 (n-n)-n-n-n-n-n-n-n-n / -1 Example: let n = 3 (3-3)-3-3-3-3-3-3-3 = -24 / -1 = 24 Proof 8*3 = 24 For 7 (n-n)-n-n-n-n-n-n-n / -1 Example: let n = 2 (2-2)-2-2-2-2-2-2-2 = -14 / -1 = 14 Proof 7*2 = 14 Alternatively: Let n and m represent the numbers to multiply together Formula is m / ( 1 / n) i.e. to multiply n=3 by m=8 x = 8 / ( 1 / 3) = 24
What is the answer to 9 over 6 equals 21 over n?
9/6 = 21/n3/2 = 21/n Since 3 x 7 = 21, then n must be 14 (2 x 7) and we have:3/2 = 21/14 or 9/6 = 21/14.
What is 5 plus 3 plus 2 equals 5 plus 3 plus n?
That would be 18+n. 5+3+2 = 5+3+n 10 = 8 + n 10-8 = n 2 = n and if you substitute 2 for n then you see that 5+3+2 = 5+3+2
What is the answer to 4 divided by 8 over n to the power of 3?
(4/8)/(n^3)...4/8 reduces to 1/2 so the problem reduces to (1/2)/(n^3)...Which written in simple terms is 1/n^3. Actually I made a typo the answer is 1/(2n^3) Sorry about that.
How do you write 3 to the power of n plus 2 plus 3 to the power of n as a single term?
3^n+2+3^n = 6^n+2 *'to the power of' can be represented with this symbol ^ .
