Answer by Leaf W.(135) (Show Source): You can put this solution on YOUR website!
Let us assign the random variable "n" to the "number" (you can choose whatever you want, such as "x" or "a" if you prefer).
*
n = number
*
"5 times a number" is like saying 5 * number. Since we said that n = number, we can change "number" to "n": 5 * n, or 5n.
*
5n = 5 times a number
*
"10 less than 5 times a number" is the same as saying "5 times a number minus 10." As a result, we get the expression 5n - 10.
*
5n - 10 = 10 less than 5 times a number
*
Therefore, an expression to represent "10 less than 5 times a number" is 5n - 10.
