five less than a number is at least 40. write and solve an inequality to find the minimum value of the number

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.
