Answer:
the answer would be she would drive 192 miles
Answer: n=5
Step-by-step explanation: You are solving for ‘n’ so you would want to get ‘n’ by itself on one side of the equation. The easiest way to do this would be to divide both sides by 3, which would make ‘3n’ turn to ‘n’ and 15 into 5.
Answer:
-2, 4, 6
Step-by-step explanation:
Answer:
The coordinates of endpoint B are (15, 5).
Step-by-step explanation:
This problem gives you the midpoint coordinates of line segment AB, and the coordinates of endpoint A. Given this, you can find the "distance" between the two points and thus the "distance" between the midpoint and point B.
Start by subtracting the the coordinates of point A from the coordinates of the midpoint.
X: 9-3=6
Y: 7-9=-2
X travels along the horizontal axis, while Y travels along the vertical axis. This means that a positive X goes right, a negative X goes left, a positive Y goes up, and a negative Y goes down.
Because you have a positive 6 for X, the line traveled 6 units right from point A to the midpoint. And because you have a negative 2 for Y, the line traveled 2 units down from point A to the midpoint.
Now, going from the midpoint to your unknown point B is simply shifting the discovered number of units right and down, or adding and subtracting from your midpoint accordingly.
M(9, 7)
B(9+6, 7-2)
B(15, 5)
