When 3n divided by 7 the remainder is 4 What is the remainder when 2n is divided by 7?
5
When the reciproral of three times a number is substracted from the reciprocal number the result is one sixth find the number?
Let n be the number, then: 1/n - 1/3n = 1/6 Solve the subtraction on the left: 1/n - 1/3n = 3/3n - 1/3n = 2/3n But we know this is 1/6, thus: 2/3n = 1/6 ⇒ 3n = 12 ⇒ n = 4 Thus the number is 4.
If n is 2 3n plus 1 equals 7?
3n+1=7 3*2+1=7
What is the nth term for 3 6 10 15 21 28 36?
The Series has the formula 3n + 1/2(n - 1)(n - 2) = 3n + 1/2(n2 - 3n + 2) which simplifies to, 1/2(n2 +3n + 2)
What is 3n plus 4 equals 7?
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
what is (3n)(3n-1)?
(3n)(3n-1) = 3n * 3n - 3n * 1 Now, perform the multiplication: (3n * 3n) = 9n^2 (3n * 1) = 3n So, (3n)(3n-1) simplifies to: 9n^2 - 3n
What is 3n to the fourth power over 3n to the third power?
3n^4 divided by 3n^3 = n
How do you get this 3n plus 2 plus (3n plus 3 - 3n plus 1)?
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
How do you get 3 to the power of n plus 2 plus (3 to the power of n plus 3 minus 3 to the power of n plus 1)?
3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.
When you add a number that has a remainder of 1 when it is divided by 3 to a number that has a remainder of 2 when it is divided by 3 then what is the remainder of the sum when you divide it by 3?
The remainder is 0.If A has a remainder of 1 when divided by 3, then A = 3m + 1 for some integer mIf B has a remainder of 2 when divided by 3, then B = 3n + 1 for some integer n→ A + B = (3m + 1) + (3n + 2)= 3m + 3n + 1 + 2= 3m + 3n + 3= 3(m + n + 1)= 3k where k = m + n + 1 and is an integer→ A + B = 3k + 0→ remainder when A + B divided by 3 is 0-------------------------------------------------------------------------From this, you may be able to see that:if A when divided by C has remainder Ra; andif B when divided by C has remainder Rb; then(A + B) divided by C will have remainder equal to the remainder of (Ra + Rb) divided by C

The gcf of the expressions 3n plus 7 and 9n is 3n?
No. 3n isn't a factor of 3n + 7. The GCF of 3n + 7 and 9n is 1.
How do you write thrice a number divided by three?
Thrice is three, "a number" can be shown as n. This is 3n. 3n/3=n
What is 3n-2w and how do you work it out?
3n-2w and how do you work it out = 1
How do you do this problem 15-3n equals n-1?
15-3n=n-1
What is n in 3n-1 equals 11?
In 3n-1 equals 11, n is 4.3n - 1 = 113n - 1 + 1 = 11 + 13n = 123n/3 = 12/3n = 4
