Answer:
60 goody bags
Step-by-step explanation:
1 kg = 1000 g
6.2 kg = 6,200 g
Empty box = 200 g
Box + goody bags = 6,200 g
Weight of Goody bags = Box + goody bags - empty box
= 6,200g - 200g
= 6,000 grams
Each goody bag = 100 g
how many goody bags are inside the box
Number of goody bag in the box = total weight of goody bag / weight of each goody bag
= 6,000 grams / 100 grams
= 60 goody bags
There are 60 goody bags in the box

Answer:
your welcome
Step-by-step explanation:
he said thank you
Firstly you have to reduce the 4 variables to a double system of equation with only 2 variables.
Let's say, first we have to eliminate Z:
Take 1st & 3rd equation & multiply each term of the 1st by (- 1). One done you add up the 1st & the 3rd & you will get:
5W - 4x + 2y = - 18
Follow the same methodology to find another equation without z. Once done you will have a system of 2 equation with 2 variable easy to solve,
At the end you will find:
w = -3
x = -2
y = -1
z = 3
