How to Calculate Midpoint?
The x-coordinate of the midpoint M of the segment
is the arithmetic mean of the x-coordinates of the endpoints of the segment
. Similarly, the y-coordinate of the midpoint M of the segment
is the arithmetic mean of the y-coordinates of the endpoints of the segment
.
Answer:
<u>The three equations:</u>
- y = 15x, wolf
- y = 10x + 15, you
- y = 5x + 20, friend
<u>Compare the equations with wolf and you and with wolf and your friend:</u>
- 15x = 10x + 15
- 5x = 15
- x = 3 seconds
It will take 3 seconds before you are caught by the wolf
- 15x = 5x + 20
- 10x = 20
- x = 2 seconds
It will take 2 seconds before your friend is caught by the wolf, he will be caught a second before you.
Answer:
n = 3
m = -1/2
Step-by-step explanation:
Multiply the second equation by 4
4(n - 2)x + y = 4(n + m) Y is now correct.
4(n - 2) = 4 Remove the brackets
4n - 8 = 4 Add 8 to both sides
4n = 8 + 4 Combine
4n = 12 Divide by 4
n = 3 x is now correct
4(n - 2) = 4
4(3 -2) = 4
4 = 4
Now you have to worry about m
4(n + m) = 10
n = 3
4(3 + m) = 10 Divide by 4
m + 3 = 10/4
m + 3 = 2.5 Subtract 3 from both sides.
m = 2.5 - 3
m = - 1/2
Answer:
60 students were in each bus.
Step-by-step explanation:
248-8=240
240 students rode on busses.
240/4= 60
