It was recently estimated that homes without children outnumber homes with children by about eight to seven. If there are 3870
homes in a county, how many of them are homes without children?

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)

answer: the answer is d

using pemdas, (order of operations) you'll see the answer is 24.
