Answer:
D
Step-by-step explanation:
If the lines are parallel, the slope of both of them are going to be the same. So if one line is 3, the other one will be too.
For quarters we have:

Where,
x: number of quarters
Clearing x we have:

For nickels we have:

Where,
y: number of nickels
Clearing y we have:

Then, the ratio of quarters to nickels is:

Simplifying we have:

Answer:
The ratio of quarters to nickels in a dollar is:

If you're looking for the gradient then it will be y=4x otherwise please write the question!
I believe its the second one because it say four times the number wich the number is the y and it is = too the number wich is y and increased going up are adding by 9. hope that helped.
Answer:
The answer is 4
Step-by-step explanation:
2x + 5 = 13
Now, Subtract 5 from both side we get,
2x + 5 - 5 = 13 - 5
2x = 8
Then, Divide both side by 2 we get,
2x/2 = 8/2
x = 4
Thus, The answer is 4
