What is the value of the expression "two less than six times the diffrence of a number and five" when n = 9?

22

Step-by-step explanation:

n=9

6 * (9-5) - 2 = 6*4-2 = 24-2

22

Step-by-step explanation:

First, let's convert this into the algebra language. Because the number is n, we have n - 5, because it is the difference of n and 5, and it says we have to multiply this by 6, so 6 (n - 5), and finally, we subtract 2 from this to get 6 (n - 5) - 2, and plugging in 9 gives 6 (9 - 5) - 2 = 6 (4) - 2 = 24 - 2 = 22.
