Identify and label each of the mathematical properties below. (Commutative, Associate, Identity, or Distributive)

1) a + b = b + a

2) (a + b) + c = a + (b + c)

3) n + 0 = n

4) c(a + b) = ca + cb

5) n - 0 = n

6) (a x b) x c = a x (b x c)

7) a x b = b x a

8) n x 1 = n

9) n / 1 = n

a. -0.3 > -0.33

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
