Answer:
The number is 19
Step-by-step explanation:
Given : Expression "48 is 9 less than 3 times a number."
We have to find the number.
Consider the given expression "48 is 9 less than 3 times a number."
Let the number be x.
Then the expression can be written mathematically as
48 is 9 less than 3 times number x
9 less than 3 times number x = 3x - 9
then 48 = 3x - 9
adding 9 both sides, we get,
48 + 9 = 3x
57 = 3x
divide both side by 3,
we have,
x = 19
Thus, the number is 19.
