Which of the following is a valid use of the associative property of addition?
A. (23 + 15) – 5 = 23+ (15 – 5)
B. (23 – 15) + 5 = 23 – (15 + 5)

Respuesta :

Answer:

A

Step-by-step explanation:

(25+15)-5=40-5=35

25+(15-5)=25+10=35

[tex]\text{Associative property:}\\\\a+(b+c)=(a+b)+c\\\\\text{Find the equation that matches with the associative property formula}\\\\\text{When you add them, you should get the same answer no matter what}\\\text{position the numbers are in}\\\\(23+15)-5\\\\38-5=33\\\\23+15-5\\\\38-5=33\\\\\text{This means that A would be your answer}\\\\\boxed{A. (23 + 15) - 5 = 23+ (15 - 5)}[/tex]
