5781.2 millimeters
Step-by-step explanation:
Answer:
The correct answer is third option
(10x² - 4) - (7x² + 3)
Step-by-step explanation:
From the given option we get the correct answer is third option.
(10x² - 4) - (7x² + 3)
<u>Check the correct answer</u>
(10x² - 4) - (7x² + 3) = 10x² - 4 - 7x² - 3)
= 10x² - 7x² - 4 - 3 = 3x² - 7
Therefore the correct answer is third option
(10x² - 4) - (7x² + 3)
Answer:
5(2a - 5 + b)
Step-by-step explanation:
I factored out a 5 from all of the terms.
Solution:
At 5:30 PM the distance between the train will be 621 miles.
Explanation:
We have been given that one train goes north and other train gores south. It means they are moving in opposite direction.
When two body moving in opposite directions then the relative velocity is the sum of their individual velocities.
Therefore, the relative speed is given by
Now, the distance between the train is 621 miles. Hence, using the relation between speed, time and distance, we have
Thus, at 5:30 PM the distance between the train will be 621 miles.
