Step-by-step explanation:
Midpoint of a segment:
The midpoint of a segment is given by the mean of its coordinates.
Segment with end points (4,2),(-5,-1)
x-coordinates: 4 and -5
y-coordinates: 2 and -1
x-coordinate of the midpoint:

y-coordinate of the midpoint:

The midpoint of the segment is (-0.5,0.5).

multiply 10 by .2
10 × .2 = 2
add 2 to 10
2 + 10 = 12 cm
 
        
             
        
        
        
| r + 3 | > 7
r + 3 > 7       r + 3 < -7
r > 7 - 3        r < -7 - 3
r > 4             r < -10
so, r > 4 and r < -10
==========================
what percent of 60 is 12
percent formula : is/of = %/100
percent = x
is = 12
of = 60
now sub
12/60 = x/100
cross multiply
60x = 12 * 100
60x = 1200
x = 1200/60
x = 20%
