Answer:
Marta
Step-by-step explanation:
We are given that
![50+\frac{1}{2}m=120](https://tex.z-dn.net/?f=50%2B%5Cfrac%7B1%7D%7B2%7Dm%3D120)
We have to find who is correct and explain.
We know that
Equation: It is mathematical sentence that combines numbers and variables which shows the equality of two expressions.
Example:
![x+y=3](https://tex.z-dn.net/?f=x%2By%3D3)
Expression: It is mathematical phrase that combines numbers and variables
using mathematical operators.It can be evaluated but not solved.
Example:
![x+y](https://tex.z-dn.net/?f=x%2By)
By definitions
![50+\frac{1}{2}m=120](https://tex.z-dn.net/?f=50%2B%5Cfrac%7B1%7D%7B2%7Dm%3D120)
It is in equation form.
Therefore, Marta is correct.

Answer:
C) 56
Step-by-step explanation:
DEG and FEG are on a straight line forming 180 degree.
Set your formula up as
180 = (3x+31)+(2x-6)
180 = 3x +2x +31 - 6
180 - 31 + 6 = 5x
155 = 5x
155/5 = x
31 = x
Now substitute 31 in place of x
FEG = (2*31-6)
FEG = 56
