The dishes have been sorted into cups and plates. the number of plates is four less than two times the number of cups. the dishes are 60% plates. how many cups are there?
a) 3
b) 6
c) 8
d) 9

Option C) 8 cups

Step-by-step explanation:

Let

x> the number of cups

y ---> the number of plates

we know that

y=2x-4 > equation A

60%=60/100=0.60

y=0.60(x+y) > equation B

Substitute equation A in equation B and solve for x

2x-4=0.60(x+2x-4)

2x-4=0.6x+1.2x-2.4

2x-4=1.8x-2.4

2x-1.8x=4-2.4

0.2x=1.6

x=1.6/0.2

x= 8 cups

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
