Well, darling, 3n - 18 is an algebraic expression where you take three times a number (n) and then subtract 18 from it. It's as simple as that. So, if you want to find the value of this expression, you'll need to know the value of n. Hope that clears things up for you, sugar.
The expression 3n - 18 represents a linear equation in one variable, n. To simplify this expression, you distribute the 3 to both terms inside the parentheses, resulting in 3n - 3(6), which simplifies to 3n - 18. This expression cannot be further simplified without knowing the specific value of n.
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.
The first, second, third, fourth, and fifth terms of 3n - 7 are as follows:1: -42: -13: 24: 55: 8
One possible answer is Un = 3n - 1 for n = 1, 2, 3, ...
The 'n'th term is [ 4 - 3n ].
3n + 8
(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
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
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.
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
Let the number be 'n' 'Thrice' means three times. algebraically it is written as '3n' 'and '8' is 3n + 8 The answer is '3n + 8' .
3n -5 = 19 3n = 19+5 3n = 24 n = 8
3n + 14 = 83n = 8 - 14 = -63n/3 = -6/3n = -2The value of n is -2.
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.
4
No. 3n isn't a factor of 3n + 7. The GCF of 3n + 7 and 9n is 1.
3n - 1
All you do is look for like terms such as 7n and 3n; 2 and 8 Then you do 7n+3n=10 n And ........... 2-8=-6 The answer is 10n-6 if you still dont get it contact me(:
