In order to have the variable by itself you have to add 20 to both sides. So your answer would be a=b+20. I hope this helps love! :)
Answer:
Juan travel 31.4 feet farther than Fred in one rotation.
Step-by-step explanation:
In this problem we need to determine the change in linear position of Fred and Juan, whose formula is:
(Eq. 1)
Where:
- Radius, measured in feet.
- Angular arch, measured in radians.
- Change in linear position, measured in feet.
If both makes one rotation in the carousel, we obtain the change in linear position of each player:
Fred (
,
)



Juan (
,
)



And the difference between both travelled distances is:


Juan travel 31.4 feet farther than Fred in one rotation.
The equation for the stand form of a line is y = mx + b.
You will need
m = slope
b = y-intercept
The question already gave you both of those so you simply put them into the equation "y=mx+b"
m = -1/2
y-intercept = 1
Plug those into "y = mx + b"
Your equation is: y = -1/2x + 1
Answer:
11+4
Step-by-step explanation:
11+4=15
