A purse contains $2.45 in dimes andquarters. There are two more than
twice as many dimes as quarters. How
many of each coin are in the purse?​

Answers

Answer:

dimes = 12, quarters =5

Step-by-step explanation:

Let x stand for quarters. So if there are two more than twice as many dimes than quarters than it would look something like

d = 2x+2

q = x

Now multiply them by the value of the coin, to get them into cents. So you'd multiply dimes by twn (2x+2*10) which is equal to 20x+20. Multiply quarters by 25. x*25=25x

Now make an equation. 20x+20+25x=245

45x=225

x=5

q = 5

d = 12

75% of what number is 27?

Answers

So we want to know the number from which we take 75% and get 27. If the number we are looking for is x, then the equation to find that x would be: (75/100)*x=27 which says seventy five percent out of x is equal 27. So, x=(27*100)/75. And finally, x= 2700/75=36. So, 75% out of 36 is 27.
