Answer: 
Step-by-step explanation:
By definition, the sum of the exterior angles of a polygon is 360 degrees.
Knowing this, you can write the following equation:

Then, you must solve for "x" in order to find its value. To do it, you can follow these steps:
1. You need to add the like terms:

2. Now, subtract 40 from both sides of the equation:

3. Finally, you must divide both sides of the equation by 4. Then:

Answer: y is going down 3 x is going up 2
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
move x to the 3x side and move 5 to 9 side.
you get 2x=4
then you divide 2 from both sides and get 2
Answer:
19683
Step-by-step explanation:
1. find the ratio
this is geometric so..
54÷18=3
18÷6=3
2. set up the problem
3(3)^9-1
3^8= 6561
6561(3)=19683
