Answer:
That would be 1.5
Step-by-step explanation:
Here it is.
The easiest way to solve this is by elimination.
3x - y = 6
6x + y = 21
Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:
9x = 27
Then solving for x leaves you with x = 3
Then you take the x value of three and plug it into to either of the equations, so
3(3) - y = 6
9 - y = 6
subtracting 9
-y = -3
then dividing by -1
y = 3
so the solution is x = 3 y = 3 or (3,3)
Answer:
C: 2m + 1
Step-by-step explanation:
If m + 1 is even, then m is odd.
A: m - 1 is even
B: 2m - 2 is even
C: 2m + 1 is odd
D: 2m + 2 is even
Answer:

Step-by-step explanation:
Given
See attachment
Required
The value of x that makes l and m parallel
Let the angles be ABC (See attachment 2)
is corresponding to 50 degrees. So:

is corresponding to 55 degrees. So:

This means that:


Solve for x


First, multiply the radius by itself. 5x5=25. Then multiply by pi, or 3.14. 25x3.14=78.5. The area of the circle is 78.5units^2. Hope this helps! ;)
