Answer:
Step-by-step explanation:
Since we know that the two lines are parallel because of alternate interior angles (5x-20)=3x
then solve for x
5x-20=3x
-20=-2x
x=10°
Answer:
8/9 (simplified)
Step-by-step explanation:
Total marbles = 18
Total of marbles <em>not</em> white = 16
Numerator = 16 / Denominator = 18
= 16/18
= 8/9 (simplified)
Answer:

Step-by-step explanation:
Two angles are supplementary when they add up to 180°.
So we know that:

Supplanting we get:

We add up the X's.


Then we send 64 to the other side adding:



And then the 8 goes dividing:


Im not going to graph it for you but the equation is
C=7250+250s
