Question

pls help. Choose the property which best suits each step.

(1/5) [(n+5) + -n] Given
=(1/5) [(5 + n) + -n] A
=(1/5) [ 5 + (n + -n)] B
=(1/5) [5+0] C
=(1/5)(5) D
=1 E

1) Additive Inverse ___
2) Commutative ___
3) Associative ___
4) Multiplicative Inverse ___
5) Additive Identity ___

ive tried looking definitions up and I dont seem to understand. thanks in advanced..

Answer 1

Additive Inverse: a+(-a)=0
Commutative: a+b = b+a
Associative: a+(b+c) = (a+b)+c
Multiplicative Inverse: x*(1/x) = 1
Additive Identity: a+0=a

1) C
2) A
3) B
4) E
5) D
