Answer:
D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Step-by-step explanation:
Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.
or, for any numbers A, B and C
A + ( B +C) = (A +B) + C
Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Answer:
x=56
Step-by-step explanation:
okay so
x=180- (64+60)
x= 180-124
x= 56
Hmmm unless you can do negatives, I'd say 10 and 0. 10 minus 0 is 10 (which fits) and the product of 10 and zero IS zero. does that make sense?
0.19579831 (that's what my math app said the estimate was)
