The sum of two numbers, x and y, is 142. their
could be used to find the numbers?
nbers,
and y, is 142. their difference is 14. which system of equations
x + 142 = y
+
18.64
x + y = 142
y = 14
b.
- 14 = y
c
x - y = 142
x + y = 14
d.
14
x=142 + y
y = 14- x
+

answer: it's d

step-by-step explanation:

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)
