How do you solve 3n-6 equals 9?
Let's give it a go:3n - 6 = 9Add 6 to each side of the equation:3n = 15Divide each side by 3:n = 5
3n plus 6 equals n plus 20?
3n + 6 = n + 202n = 14n = 7
How do you do 3n plus 6 equals -9?
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -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.
What is the value of n if one angle in a pair of vertical angles measures 30 degrees and the other measures 3n-6?
Vertical angles are always equivalent. Therefore, we know that if the first vertical angle measures 30 degrees, the other must measure 30 degrees as well. So, since the second vertical angle has a value of 3n-6, we can set this equal to 30 degrees yielding the equation 3n - 6 = 30. From here, we just need to do some simple algebra: 3n - 6 = 30 3n = 36 n = 12 To find the value of n.
Which experssion is equivalent to 9n 3 after combing like terms?
9n+6-3n
The product of a number and 3 is 6?
6=3n or 3n=6
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
What is 3n plus 6 equals 18?
3n+6=18 n+2=6 n=4
What are the equivalent fractions for 6 10ths?
3/5, 9/15, 12/20, 3n/5n for all n = 5, 6, 7, ...

3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
What is 15 9 plus 3n?
Assume the expression is: 15 = 9 + 3n Subtract both sides by 9 to get: 15 - 9 = 9 - 9 + 3n 6 = 3n Finally, divide both sides by 3 to get: 6/3 = 3n/3 n = 2
