Answer: 
Step-by-step explanation:
For this exercise you need to remember the following formula:
Where "V" is the speed, "d" is the distance and "t" is time.
In this case, according to the information given in the exercise, you know that:
- James leaves his school at 3:15 and arrives at the park at 3:25. Then, you can identify that the time it takes him to go from his school to the park is:
- The park is 0.5 miles from James' school. Therefore, you can identify that "d" is:
So, knowing those values, you can substitute them into the formula:
Finally, evaluating, you get the following result:
Answer:
4(5 - 7x) = 6 - 12
20-28x=6-12x
Subtract 20 from both sides
20-28x-20=6-12x-20
Simplify
-28x=-12x-14
Add 12x to both sides
-28+12x=-12x=-12x-14+12x
Simplify
-16x=-14
Divide both sides by -16
-16/-16 = -14/-16

Answer: The sailboat is at a distance of 15 km from the port.
Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.
We are to find the distance between the sailboat from the port in kilometers.
Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.
The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.
PS = ?
Using the Pythagoras theorem, we have from right-angled triangle SOP,
Thus, the sailboat is at a distance of 15 km from the port.
