Answer:
d=rt
r=420 per hr, 3 hrs = 420/3= 140
t=1
d=140×1=140miles
The answer is A, because the ocean floor is -5 or below the sea level,so that makes the sea level=0, and the summit is 5km because if the whole thing is 10 km above the ocean floor, so 10+(-5)=5km.
Subtract the point A x-coordinate from the midpoint x-coordinate (final-initial) to find the distance between them. This will give you 3. Multiply the by 2 because the midpoint is halfway between point A and B.
Answer:
no solutions
Step-by-step explanation:
4x + 2y = –14
6x + 3y = –22
Divide the first equation by 2 and the second equation by 3
4x/2 + 2y/2 = –14/2 2x +y = -7
6x/3 + 3y/3 = –22/3 2x + y = -22/3
The left hand sides are the same but the right hand sides are different.
Multiply the second equation by -1
2x+y = -7
-2x -y = 22/3
-------------------
0 = -7+22/3
0 = 1/3
This is never true, so there are no solutions
