In the figure we have three parallel lines cut by two transversals
The theorem stares:
If two or more parallel lines are cut by two transversals, then they divide the transversals proportionally.
Applying this theorem we have:

To solve for x we cross multiply
6x=20
Dividing both sides by 6 we have:

The second option x=
is the right answer
Answer:
25%
Step-by-step explanation:
55 + 12 + 88 + 45 + 9 + 91=300/12=25=25%
Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
