First Let we solve the Original system of equations:
equation (1): 
equation (2): 
Multiplying equation (1) by 7, we get


Subtracting,
implies 
Then
Thus the solution of the original equation is
Now Let we form the new equation:
Equation 2 is kept unchanged:
Equation (2):
Equation 1 is replaced with the sum of equation 1 and a multiple of equation 2:
Equation (1): 
Now solve this two equations: 
Multiply (1) by 7 and (2) by 8,


Subtracting,
implies 
Then x=2.
so the solution for the new system of equation is x=2, y=1.
This Show that the solution to the system of equations 8x − 5y = 11 and 7x − 8y = 6 is the same as the solution to the given system of equations

8/8= 1
Answer:
The awnser might be 21.25 because you have to divide 8 by 6 then multiply 15 then you will get your awnser
Step-by-step explanation:
Answer: 1.455 km
Step-by-step explanation:
First lets convert 145,500 cm in m.
145500 × 10^-2 m ( NOTE that c = 10^-2 )
= 1455 m
Now convert 1455 m in km.
1455× 10^-3× 10^3 m
= 1455 × 10^-3 km (NOTE that k= 10^3)
= 1.455 km
