Answer:
Number of nickels = 6
number of dimes = 9
number of quarters =12
Step-by-step explanation:
Let 'q' be the number of quarters and 'n' be the number of nickels
and 'd' be the number of dimes
twice as many quarters as nickels
three more dimes than nickels.
1 nickel = 5 cents
1 dime = 10 cents
1 quarter = 25 cents
4.20 dollars = 420 cents
replace q and d in the above equation
Subtract 30 from both sides
divide both sides by 65
n=6
Number of nickels = 6
number of dimes = 
number of quarters =

Answer:
the point where the two coordinates meet
Step-by-step explanation:
The answer is : B
-Hope this helps, even though you asked for no explanation.
A reflection over the x axis coupled with another reflection over the y axis leads to a rotation of 180 degrees.
In other words,
Start with point A. Reflect over the x axis to get point B. Reflect B over the y axis to get point C. To go from A to C, we can rotate A 180 degrees about the origin.
----------------
So this means that if we do those reflections and then do the rotation, then we end up back where we started. Wherever point A is located, the point A' will also be located at the same position with the same coordinates.
