Answer:
Hence the System of equation are
There are 5 dimes and 7 quarters in my pocket.
Step-by-step explanation:
Let Number of dimes be 'x'.
Also Number of quarters be 'y'.
Now Given:
Total Number of Coins = 12
So the equation can be framed as;
Also Given:
Total Amount in pocket = $2.25
Now we know that 1 dime = $0.1
Also 1 quarter =$0.25
So the equation can be framed as;
Hence the System of equation are
Now Solving the equation we get;
Now Multiplying equation 2 by 10 we get;
Now Subtracting equation 1 from equation 3 we get;
Now Substituting the value of y in equation 1 we get;
Hence there are 5 dimes and 7 quarters in my pocket.
