Chris has $3.30 in nickels and quarters. if she has twice as many quarters as nickels, how many of each coin does she have?

Chris has 12 quarters and 6 dimes

Step-by-step explanation: Lets have x be the number of quarters and y be the number of nickels. If she has twice as many quarters as nickels, then we already have our first equation: x=2y! To get the second equation, you put the real world value of quarters and nickels next to their variable and have it equal the total amount of money she has ($3.30), so the equation should look like this:

.25x + .05y=3.30

The next step is easy, just solve by substituting the equations into each other! So:

If x= 2y then,

.25(2y) + .05y= 3.30

.5y + .05y= 3.30

(.55y= 3.30)÷ .55

y= 6

And if y (which is the number of nickels!) equals 6, then we can plug that back into the x= 2y equation! So:

x= 2(6)

x= 12

Thus, Chris has 12 quarters and 6 nickels! Hope this helps!

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
