Answer:
a. x = (2 -3y)/(y+3)
b. x = -4/5
Step-by-step explanation:
<h3>a.</h3>Clear the fraction, collect x terms, divide by the coefficient of x.
__
<h3>b.</h3>Put 2 where y is and do the arithmetic.
x = (2 -3(2))/(2 +3) = (2 -6)/5
x = -4/5

Answer:
v = 3.64 ft/s
Step-by-step explanation:
Given that,
Radius of a carousel, r = 18 feet
It takes 31 seconds to complete revolution.
We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.
d = 2πr
d = 2π × 18 = 113.09 feet
Let v is the linear speed. It can be given by :
So, the linear speed of the carousel is 3.64 ft/s.
