Answer
180°-(49+90+x)
x=180°- 139
X=41°
Step-by-step explanation
Answer:
the slope is 2/3 bcoz u do 2-0/3-0
C.
he starts 6500 ft up do that's the b in y=mx+b.
the m is -250 because that's the rate, and it's negative because he's going down.
The statement is false, as the system can have no solutions or infinite solutions.
<h3>
Is the statement true or false?</h3>
The statement says that a system of linear equations with 3 variables and 3 equations has one solution.
If the variables are x, y, and z, then the system can be written as:

Now, the statement is clearly false. Suppose that we have:

Then we have 3 parallel equations. Parallel equations never do intercept, then this system has no solutions.
Then there are systems of 3 variables with 3 equations where there are no solutions, so the statement is false.

12 times 2 plus 16 times 2 is 56.
144 + 256 = 400
400 = Xx2
X = 20 feet.
