For this case we give as data the following equation:
Where "x" represents the cost of a ticket.
By clearing the value of "x" of the equation we can know the cost of a ticket.
If we subtract 12 from both sides of the equation, we have:
If we divide between 4 on both sides of the equation:
Therefore, the cost of a ticket is $ 9.00
Answer:
Option C
Using proportions, it is found that he bikes:
- 28.5 miles in one and a hour.
- 47.5 miles in two and a hours.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, the proportion is that he bikes 9.5 miles each half hour, hence:
- In one hour, he bikes 2 x 9.5 = 19 miles.
- In one and a half hour, he bikes 3 x 9.5 = 28.5 miles.
- In two hours, 4 x 9.5 = 38 miles.
- In two and a half hours, he bikes 5 x 9.5 = 47.5 miles.

Answer:
2.34 yards
Step-by-step explanation:
First add all the yards together
23 + 11.1 + 24.4 = 58.5
If this is used to make 25 quilts you will divide your previous answer by 25 to find how much is used for one quilt
58.5/ 25 = 2.34
Since the real track has a gauge of 3 feet but the model railroad track has a gauge of 3/4 inches, the scale factor must be 1/4, because you must follow the rule
"true measurement * scale factor = model measurement"
In fact, we have
This implies that the original driving wheels height, 44 inches, must be scaled down to
inches.
