Answer:
x = 12
Step-by-step explanation:
Angle GHK is half of 120, so is 60. Then ...
3x +24 = 60
3x = 36 . . . . . subtract 24
x = 12 . . . . . . . divide by 3
The unit rate is a ratio of change in y and into the change on x. It can also be the rise to run or the slope.

Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:

As you can see, x increases in steps of 1 units. So let's check the difference in y:

So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:

Then:

Finally, the equation of the line is:

Answer:
x=771
Step-by-step explanation:
−771 + x = 0
x − 771 = 0
x − 771 + 771 = 0 + 771
