The number of quarters she have 11.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let consider y = quarters; x = dimes
We know that there are 3 times as many dimes as quarters. So we can state that x = 3y.
Then, we say that 25y + 10x = 605
(Value of coin * amount of coins)
Then we substitute x=3y into the equation, yielding:
25y + 10(3y) = 605
25y + 30y = 605
55y = 605
605/55 = 11 = y
Therefore, the number of quarters she have 11.

The simplest form is 15/28
Correct me if I'm wrong. Hope this helps!
Well, put x=0 then y=4
x=6 y=0
x=3 y=2
Now plot the graph :)
It would go over the five, so im guessing the hundreds
Answer:
All of them
Step-by-step explanation:
none of the graphs repeat any numbers on the x
