Answer:
x = the number
Step-by-step explanation:
15.) 2x + 9 = 25
16.) 3x - 6 = 21
17.) 7x = 12 + 3x
18.) 4x = 18 + x
19.) 2x + 24 = 8x
20.) 30 - x = 4x
Answer:
y=2/4x+5/2
Step-by-step explanation:
y=mx+b
2-4/-1-3
-2/-4
Slope =2/4
y=2/4x+b
2=2/4(-1)+b
b=5/2
y=2/4x+5/2
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:
