Question

Use the properties of real numbers to simplify each expression (5+29)+65

Answer 1

See explanation

Explanation:

Consider the expression

`(5+29)+65`

First, use the commutative property over addition:

`(5+29)+65=65+(5+29)`

Then, use the associative property over addition:

`65+(5+29)=(65+5)+29`

Now, it is easy to add 5 and 65:

`65+5=70,`

so

`(65+5)+29=70+29=99`
