Use the associative property to determine if the equations are equal:

6 + (2 + 20) _______ 5 + (2 + 20)

7 answers

6 + (2 + 20) = 6 + 22 = 28
5 + (2 + 20) = 5 + 22 = 27

Since 28 is not equal to 27, the equations are not equal.
Will the next number in the pattern be greater than or less than 11?

5, 7, 9, 11, __
Since the given pattern is increasing by 2 each time, the next number would be 13. Therefore, the next number in the pattern is greater than 11.
What will be the next number in this pattern?

18, 14, 10, 6, __
The pattern is decreasing by 4 each time. Therefore, the next number in the pattern would be 2.
