Answer:
x ≤ 435
Step-by-step explanation:
Given is the following condition.
The sum of a number and 15 is less than and equal to 450.
So, if the number is x, then we have
x + 15 ≤ 450
⇒ x + 15 - 15 ≤ 450 - 15
⇒ x ≤ 435
Therefore, the solutions of the number are either 435 or less than 435 up to negative infinity. ( Answer )
