The place where your "m" is already correct.
Additive inverse of -3(1/4) would be a number which when added to -3(1/4) would equal to 0. (zero)
This number is 3(1/4).
-3(1/4) + 3(1/4) = 0
If you were to count, it takes 8 little of those lines/stems thingy in order to reach the whole next number.
(1/4) of 8 is 2 so "m" would be at 2 little line/stems to the right of 3 which is where you already left it at.

The sum of two segments are 75 cm, and one the segments are four times the other. Calculate the measurement of each segment

iVinArrow [24]

The length of one segment is 15 cm and other segment is 60 cm

Step-by-step explanation:

Let x be the length of one segment and y be the length of other segment

Then according to given statement

x+y=75 Eqn 1

And

one the segments are four times the other

x=4y Eqn 2

$Putting\ x=4y\ in\ equation\ 1$

$4y+y=75\\5y=75\\Dividing\ both\ sides\ by\ 5\\\frac{5y}{5}=\frac{75}{5}\\y=15\\Putting\ y=15\ in\ eqn\ 2\\x=4(15)\\x=60$

Hence,

The length of one segment is 15 cm and other segment is 60 cm
