The number of quarters in sarah's purse is one less than twice the number of dimes she has. if the dimes and quarters total $3.95, how many dimes does she have?

7 dimes

Step-by-step explanation:

Let

x> the number of quarters

y> the number of dimes

Remember that

1 quarter=$0.25

1 dime=$0.10

we know that

0.25x+0.10y=3.95 > Multiply by 100 both sides

25x+10y=395 > equation A

x=2y-1 > equation B

substitute equation B in equation A

25(2y-1)+10y=395

solve for y

50y-25+10y=395

50y+10y=395+25

60y=420

y=7 dimes

step-by-step explanation:

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.
