Use an associative property to write an equivalent expression.
2r + (19s + 22)
(2r+19s)+22
To use the associative property to write an equivalent expression, we need to rearrange the terms while keeping the grouping symbols in place. The associative property states that the grouping of numbers in an addition or multiplication operation does not affect the result.
In the given expression, we can start by grouping the terms differently like this:
(2r + 19s) + 22
By moving the grouping symbol, we've changed the grouping of the terms, but not the actual calculation. Therefore, the expression 2r + (19s + 22) is equivalent to (2r + 19s) + 22.
