Answer:
take your pick. Each has its own reason.
Step-by-step explanation:
As with a lot of "doesn't belong" problems, the one that is different depends on your criteria. In the attached figure, each one "doesn't belong" for a different reason. Those reasons are listed below each number line.

I might choose the lower left: "addition, not subtraction", as it is the only one with arrows in the same direction. That makes its difference from the others more obvious, perhaps.
For this case, the first thing we must do is define variables.
We have then:
d: number of dimes
q: number of quarters
We now write the system of equations that models the problem.
We have then:
He has a total of 30 coins:

The toal value of Kyles coins is $ 4.80:

Answer:
A system of equations that can be used to find the number of dimes, d, and the number of quarters, q, kyes has is:


5

5 x 8 = 40
6 x 1 = 6
40 / 6 = 6

= 6 2/3
(hope I'm right & this helps you!)
