0.1m+8-12 when m=30 and n=1/4

Look at this

Substitute the given numbers and do the arithmetic.

... 0.1·30 + 8 - 12·(1/4) = 3 + 8 - 3 = 8

Step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

50- 250 is correct i did that one too
