For points a(−4, 8) and b(6, −14), what is the y-coordinate of the midpoint of line segment ab? ! will give brainliest

the y coordinate of the midpoint is -3

Step-by-step explanation:

To find the midpoint

midpoint = (x1+x2)/2, (y1+y2)/2

the y coordinate =  (y1+y2)/2

                             = (8+-14)/2

                             = -6/2

                            = -3

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
