Answer:
x = 1
Step-by-step explanation:
Given equation:

Now,
subtracting
from both sides
we get
⇒ 
or
⇒ 
or
⇒ 
or
⇒ 
or

Now, multiplying both sides with the number 2, we get
x = 1
The second one. 4/6 and 2/3
Answer:
6x^2+2x
Step-by-step explanation:
The angular speed of the wheel is calculated as 52.36 radians per second
<h3>How to solve for the angular speed</h3>
The revolution of this wheel is said to be at 500 in a minute
This is also called the frequency of this wheel.
This can be written as
500rev in 60 seconds. 500/60 = 8.333 per second
Angular speed is given as
pi = 22/7
f = 8.333
Formular for angular speed = ω = 2*pi*f
w = 2 * 22/7 * 8.333
= 52.36 radians per second
