Answer: 
and 
Step-by-step explanation:
To solve the system of equations with the linear combination method, you must:
- Arrange the equations in a colum.
- Make one of the set of terms, with equal variables, opposite in signs but equal in coefficients.
- Add both equations to cancel out that set of terms.
- Solve for the the variable left.
- Substitute the value of that variable into one of the original equations and solve for the other variable to find its value.
As you can see, the first equation of the system of equations given in the problem, does not have the variable 
, so you can't apply the proccedure shown above. Then, to solve it you must:
-Solve for 
in the first equation:
- Substitute the value obtained into the second equation and solve for , then:
Therefore:
and
Answer:
Step-by-step explanation:
Supplementary means that 2 angles add up to 180 degrees.
If ACB and ACD are supplementary then they have to add up to 180 degrees.
We know that ACD is smaller than ACB and EGF is supplementary to the smaller of the two.
So then these two are supplementary.
If these are supplementary then the only reason i can think of is that they are supplementary or not. I recently had a test on this too and i may have failed. I have given you all the information i know. Sorry. If it is multiple choce then pick a random one. You may get it correct.

I'm pretty sure this is right? Unless I'm missing something, if I am I am terribly sorry.
Answer:
Step-by-step explanation:
A=P(1+rt)
A=200(1+.02(3))
A=200(1.06)
A=$212
