When the minimart opened, there were 178 bags of chips on the shelf. The clerk sold some chips. During the day, the clerk put 72
more bags on the shelf. When the store closed, there were 57 bags
on the shelf. How many bags were sold?

193 bags

Step-by-step explanation:

178 - x + 72 = 57

250 - x = 57

x = 193

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

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)
