Answer: The first number is 4
Explanation: Since the sum of the two numbers is ten, x + y = 10
Also, since the difference of the two numbers is two, then x - y = 2
Since x - y = 2, another way to write that is x = y + 2 and since x is exactly the same as y + 2, we can plug in "y + 2" in place of x in the first equation (x + y = 10) to get (y + 2) + y = 10. Then we solve this equation by combining like-terms.
2y + 2 = 10
2y = 8
y = 4
Since x = y + 2, x = 4 + 2 or x = 6
I hope this helped you!

<h2><u><em>
242.5226626 mph</em></u></h2>
Step-by-step explanation:
1 ft/s = 0.681818 mph
355.7 * 0.681818 = 242.5226626
355.7 ft/s = 242.5226626 mph
Answer:

Answer:
Point A is
miles far from point B.
Step-by-step explanation:
Draw a diagram by using the given information.
1. Move 8 units up to reach at point Q. (Walk from point A ,8 miles due north).
2. Move 5 units right to reach at point R. (5 miles dues east)
3. Move 4 units down to reach at point B. (4 miles due north to point B)
4. Drawn a line PB as shown below.
From the below figure it is clear that
AP = 8-4 = 4 miles
PB = QR = 5 miles
Using Pythagoras we get




Taking square root on both sides.

Therefore, point A is
miles far from point B.
