20x-1000 +4000 = 60x
20x-60x= -4000 +1000
-40x= -3000
x= -3000/-40

Answer:
45 degrees
Step-by-step explanation:
An octagon is 360 degrees and 360 divided by 8 is 45.
Answer: First option. y-15=5(x-3)
Solution:
We can take any pair of points of the table. For example:
P1=(3, 15)=(x1, y1)→x1=3, y1=15
P2=(5, 25)=(x2,y2)→x2=5, y2=25
And we can find the slope m using the following formula:
m=(y2-y1)/(x2-x1)
m=(25-15)/(5-3)
m=(10)/(2)
m=5
Now we can apply the point-slope formula to find the equation of the right line:
y-y1=m(x-x1)
Replacing y1=15, m=5, and x1=3
y-15=5(x-3)
21(x+ 50) = 1,071
Use distributive property, multiply 21 by both terms inside the parenthesis:
21x + 1,050 = 1,071
Subtract 1,050 from both sides:
21x = 21
Divide both sides by 21:
x = 21/21
x = 1
