Answer:
45
Step-by-step explanation: 
5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.
x-5 ≥ 40
x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)
∴x   ≥ 45
In other words, x is at least 45.
Therefore, the minimum value of x is 45.
