Which equation applies the associative property of multiplication? ​A) 1/2⋅(5/8+3/6)=(1/2⋅5/8)+(1/2⋅3/6) ​
B) ​(−4/11−2/3)−3/4=−4/11−(2/3−3/4)​ ​C) −12/5⋅(7/12⋅1/9)⋅8/5=(−12/5⋅7/12)⋅( 1/9⋅8/5) ​
​D) 4/9⋅(−3/8)⋅9/4=4/9⋅9/4⋅(−3/8)

C) −12/5⋅(7/12⋅1/9)⋅8/5=(−12/5⋅7/12)⋅(1/9⋅8/5)

the answer

b. they are parallel and will never intersect.

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
