Answer:
since those 2 lines are parrelel that means the angles are the same so
8x+6=4x+38
minus 6
8x=4x+32
minus 4x
4x=32
divide by 4
x=8
Hope This Helps!!!
7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
F=1
Add 22 to both sides, then divide both sides by 3
Let x represent number of hours after noon.
We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be
.
We are also told that Eddie leaves the same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.
As Eddie walks in the same direction at a speed of 5 miles per hour. So distance covered by Eddie in x hours would be
.
Total distance covered by Sara when Eddie will start would be
.
Now we will equate distance covered by both in x hours as:
![5x=4x+4](https://tex.z-dn.net/?f=5x%3D4x%2B4)
Let us solve for x.
![5x-4x=4x-4x+4](https://tex.z-dn.net/?f=5x-4x%3D4x-4x%2B4)
![x=4](https://tex.z-dn.net/?f=x%3D4)
Since x represents number of hours after noon, so 4 represents 4 hours after noon.
Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.
Sample B because more people from the school are answering, giving a more accurate number
