Help pleaseee!! I put 50

a) 86

b) 12.22222222... or 110/9

Step-by-step explanation:

F(30) = 1.8(30) + 32 = 86

F(C) = 10

10 = 1.8C + 32

-22 = 1.8 C

C = 12.222222222... or 110/9

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)
