A line = 180 degrees
so z = 180 - 124
z = 56
Answer:
r = 
Step-by-step explanation:
In order to make 'q' the independent variable in the equation, you need to solve for 'r'. The dependent variable would be 'r' because it depends on the value of 'q' to be solved. We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':
-7q + 12r = 3q -4
Add '7q' to both sides: -7q + 7q + 12r = 3q - 4 + 7q or 12r = 10q - 4
Divide all terms by 12: 12r/12 = 10q/12 - 4/12
Simplify: r =
Answer:
The answer would simply be m = (8 + 3n)/4
Step-by-step explanation:
If you look at the question closely, you have two variables, and you have not been given the value for any of them, so we have to solve this algebraicly.
First, we need to get m on one side, and so we add 3n to both sides to get rid of it.(We should have 4m = 8 + 3n)
Next, we need to isolate m, we need to get it alone, by itself to get the answer, so we divide by 4 on both sides.
The expression on the right side(8 + 3n) has to be divided by 4 fully, and so your answer would simply be m = (8 + 3n)/4.
If you need more confirmation, plug in the whole expression into the given expression to check your answer.

Answer:
464
Step-by-step explanation:
Initial number of channels = 486
Additional channels = 129
Number of channels removed = 151
To obtain the number of channels he has now :
We Take the sum of the number of initial and additional channels, then we subtract the number of channels removed :
Number of channels he has now :
486 + 129 - 151 = 464
