+ closed

- closed

* closed

÷ not closed

Step-by-step explanation:

When you add integers, you will always get an integer so it is closed under addition

When you subtract integers, you will always get an integer so it is closed under subtraction

When you multiply integers, you will always get an integer so it is closed under multiplication

When you divide integers, you will not always get an integer so it is not closed under division

1/5 = .2 which is not an integer

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
