Answer: A. 0.10q+0.25d=2.85
q+d=18
Step-by-step explanation:
The system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag is q+d=18 and 0.25q+0.10d=2.85.
Given that, a bag contains 18 coins consisting of quarters and dimes. The total value of the coins is $2.85.
We need to find which system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag.
What is the system of equations?In algebra, a system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."
The number of quarters, q, and the number of dimes, d, in the bag.
Now, the number of quarters + the number of dimes=18
⇒q+d=18
The total value of the coins is $2.85.
So, 0.25q+0.10d=2.85
Therefore, the system of equations can be used to determine the number of quarters, q, and the number of dimes, d, in the bag is q+d=18 and 0.25q+0.10d=2.85.

Equation: 14=31.7-3x
Subtract 31.7 on both sides:
14=31.7-3x
-31.7 -31.7
Solve:
-17.7=-3x
Divide -3 on both sides:
-17.7/-3=-3x/-3
Answer:
x=5.9 or 5.9=x

Explain when you would use miles versus when you would use inches to reference a length measurement.
Answer:
You would use miles when describing a long distance.
Step-by-step explanation:
For example, when describing how far away is a city from another city you would use miles. That is because you are describing a long-distance and inches would be a very larger number and hard to tell how far it really is.
