How do you find the coordinates of the midpoint M of a line segment AB with endpoints A(x1, y1) and B(x2, y2)?

Back

The coordinates of the midpoint M are given by M = ((x1 + x2)/2, (y1 + y2)/2).

If M is the midpoint of segment AB, and AM = 5x + 10 and MB = 4x + 16, how do you find the value of x?

Back

Set AM equal to MB, then solve for x: 5x + 10 = 4x + 16.

If AM = 4n - 40 and MB = 7(-2n + 2), how do you find the value of n when M is the midpoint?

Back

Set AM equal to MB, then solve for n: 4n - 40 = 7(-2n + 2).

If AB = 2x + 3, BC = 3x - 5, and AC = 38, how do you find the value of x?

Back

Set up the equation AB + BC = AC, then solve for x: (2x + 3) + (3x - 5) = 38.
