What is the midpoint of a line segment that begins at the origin (0, 0) and has its endpoint at (-5, -12)?​

The midpoint is (-2.5, -6)

Step-by-step explanation:

To find the x coordinate of the midpoint, average the x coordinates of the endpoints

(0+-5)/2 = -5/2 = -2.5

To find the y coordinate of the midpoint, average the y coordinates of the endpoints

(0+-12)/2 = -12/2 = -6

The midpoint is (-2.5, -6)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
