Find the midpoint of the line segment with end coordinates of:
Arisa [49]

Answer:

The midpoint of this line segment is (-1.5, -4.5).

Step-by-step explanation:

In finding the midpoint of a line segment we are actually averaging the x- and y-coordinates of the endpoints:

                                             -2 -1

x-coordinate of midpoint = --------- = -3/2 = -1.5

                                                 2

                                              -4 -5

y-coordinate of midpoint = ---------- = -4.5

                                                   2

The midpoint of this line segment is (-1.5, -4.5).

Okay, I'm going to be adding more but what is 4/10 x 3?
Marat540 [252]

Answer:

6/5 or 1 1/5

6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)

Step-by-step explanation:

4/10*3

They both need to be a fraction, and any number over 1 = that number. So,

4/10*3/1

4*3=12

10*1=10

12/10

Then, you have to simplify the fraction.

6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)

or 1 2/10= 1 1/5

Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.
