Answer:
Please check the explanation.
Step-by-step explanation:
Given the equations


solving the system of the equations
Arrange the equation variables for elimination






solve

Divide both sides by -3






Therefore, the solutions to the system of the equations are:

But, it seems none of the options is true.
It would be D because 0.0016*250,000= 400 and 250,000-400=249600
1 is 21
2 is 47
i'm not sure what 3 is but i think it's 1.5 or 3/2
4 is 5(n+9)
A straight line is 180. To find the angle of b, you minus 39 from 180.
180-39=141
The answer is b=141
