Sarah has a collection of nickels, dimes, and quarters worth $22.25. she has 10 more dimes than nickels and twice as many quarters as dimes. how many coins of each kind does she have?

She has 35 dimes, 25 nickels and 70 quarters.

Explanation

Suppose, the number of dimes is

As there is 10 more dimes than nickels, that means number of nickels is 10 less than dimes. So the number of nickels

Also, there is twice as many quarters as dimes. So, the number of quarter

We know that, value of each dime, nickel and quarter are  $0.10 , $0.05 and $0.25

The total value of all coins is given as $22.25   So, the equation will be......

So, the number of dimes is 35 , the number of nickels is (35-10)= 25 and the number of quarters is (2×35)= 70

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
