Answer:
It was Romania, so Spain.
Answer:
55
Step-by-step explanation:
Amir picked 20, Becky picked 15 more which is 35
all together they picked 20 + 35 = 55
The first property is commutative ( the numbers 38 and 677 are swapped over)
Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)
then the additive inverse ( 38 + (-38) = 0
and finally to get the 677 we use the additive identity property.
