Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
Multiply -x+8y=22 by 5: -5x+40y=110
so adding the equations
solve 36y = 144 for y:
divide both sides by 36
Simplify
For 5x-4y=34 plug in y=4
Add 16 to both sides
Simplify
Divide both sides by 5
Simplify
Therefore, the solution to the system of equations is:

Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs
