Basically there are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is just changing the order of the addends. Example: 26+19+34+21= 21+34+19+26
Identity Property is just adding a 0 to the number that doesnt change anything. Example: 26+19+34+21 +0 = 100
Associative property is just changing the grouping of the addends. Example: (26+19) + (34+21)
I know these properties may be complicated i know inhate them too haha but i hope i helped :) if you want you can search up the distributive property too but its with multiplication and addition combined and its harder but i think these are the 3 main properties.
Of you have 3 squared you get 9 then 2 times -2 is -4. then you add them 9=-4 which would be ...A: 5
First you find a common denominator, which is 12 ( as 4,3 and 6 all go into 12). So 2/4 becomes 6/12, as 4 multiplied by 3 is 12 and whatever you do to the denominator you must do to the numerator. Then 2/3 becomes 8/12. And 2/6 becomes 4/12. If you put these in order the answer is:
2/6, 2/4, 2/3
Answer:
1 Dime
14 Quarters
Step-by-step explanation:
d + q = 15
0.10d + 0.25q = 3.60
d = 15 - q
0.10d + 0.25q = 3.60
0.10(15 - q) + 0.25q = 3.60
1.5 - 0.10q + 0.25q = 3.60
0.15q = 3.60 - 1.5
0.15q = 2.1
0.15q/0.15 = 2.1/0.15
q = 14
d = 15 - q
d = 15 - 14
d = 1
