Answer:
The eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Step-by-step explanation:
We know that Velocity = distance / time
If the eastbound train travels at x miles per hour, the westbound train travels at x + 4 mph.
After 3.5 hours, they are 658 miles apart. If we solve for distance the formula given above we have: Distance = velocity x time. We have that the total distance between both trains is 658 miles.
Substituting the values of the problem and solving for x we have
Thus, the eastbound train travels at 92 mph and the westbound train travels at 96 mph.
Answer: 21600
216 as a percentage of certain number x can be calculated by dividing 216 by x, and multiplying the result by 100. For example, 216 as a percentage of 10 = (216 / 10) x 100% = 2160%.

Answer:
B. (6, 8)
Step-by-step explanation:
To figure this out, you can plug in the coordinates to see if you get matching answers. Since you believe answer "B," is correct, we can check:
y - 8 = -3(x - 6)
8 - 8 = -3(6 - 6)
0 = -3(0)
0 = 0
<u>Since the answers match, that makes answer "B," correct.</u>
Answer:
5/16
Step-by-step explanation:
We need to change the mixed number to an improper fraction to find the reciprocal
3 1/5 = (5*3+1)/5 = 16/5
The reciprocal of 16/5 is found by flipping the fraction
5/16
20(x+17)
20×x+20×17
20x+340
