Please help me with this

Step-by-step explanation:

You have to look at what's in the drop down boxes.

Then, you have to choose a number for every box, but make sure that the numbers make sense in the equation.

47 - 90 = 43

43 - 180 = x

x = 137

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
