Answer:
[tex](3 + 9) + 10 = 3 + (9 + 10)[/tex]
[tex]12 + 10 = 3 + 19[/tex]
Step-by-step explanation:
Given
[tex](3 + 9) + 10 = 22[/tex]
Required
Create equivalent expressions using associative property of addition
This property states that:
[tex](a + b) + c = a + (b + c)[/tex]
So, the expression can be rewritten as:
[tex](3 + 9) + 10 = 3 + (9 + 10)[/tex]
Solve the expression in bracket
[tex]12 + 10 = 3 + 19[/tex]
[tex]22 = 22[/tex]
