Answer: The required equation that can be used to determine the number of dimes, x in the pocket is
Step-by-step explanation: Given that Louis has three more quarters than dimes in his pocket and a total of $1.80.
We are to find the equation that could be used to determine the number of dimes, x.
The number of dimes in the pocket is represented by x.
Since there are three more quarters than dimes, so number of quarters will be
(x + 3).
We have
1 quarter = $ 0.25 and 1 dime = $ 0.10.
There are a total of $1.80 in the pocket, so we can write
Thus, the required equation that can be used to determine the number of dimes, x in the pocket is
