You have a total of 52 dimes and quarters. you have 10 more quarters than dimes. which system of equations can you use to find the number x of quarters and number y of dimes you have? use the system to determine how much money you have in quarters and dimes.
$7.75 in quarters and $2.1 in dimes.
If we let represent the number of quarters, and let represent the number of dimes, then we have the equation
this says that the total number of dimes and quarters is 52.
And since there 10 more quarters than dimes
which can be rewritten as
this says that you have 10 more quarters than dimes.
Thus we have the system of equations
and solve this system by subtracting the second equation from the first equation to get:
we have got 21 dimes.
Now we substitute into equation (1) and solve for :
we have got 31 quarters.
Since a quarter is worth $0.25 and a dime is $0.1, the amount of money we have is
in quarters dollars
and in dimes dollars.
answer is d-29
since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
