Answer: no
Step-by-step explanation:
Answer:
Option C
The student's conclusion is correct because the solution to the system of equations
and
is 
Step-by-step explanation:
Let
x------> the cost of each burger
y-----> the cost of each sandwich
we know that
-----> equation A
----> equation B
Solve the system of equations
Multiply the equation B by 
----->
------> equation C
Adds equation A and equation C

Substitute the value of x in the equation B



The solution of the system of equations is the point 
so
The price of each burger is 
The price of each sandwich is 
130 degrees is the total degrees of the angle,
So if part of that angle was 70 degrees with a missing part you can just subtract to find the missing angle.
(130-70=60)
The missing angle equals 60 degrees
The correct answer would be B. Hope this helps, and please mark me the brainliest, we can be friends!!
