How do i solve 2x+6>20

1 answer:

4 0

Hello!

To solve 2x+6>20, you'll first need to subtract. First, you'll need to subtract 6 from 20 (20-6). Now if the 6 was negative, you would need to add 6 to 20, but for this equation you'll subtract.

2x>14

Now you will need to divide both sides by 2. Once you've done that you'll have your answer of...

x>7

I hope this helps!

The number of right-handed students in a math class is nine times the number of left-handed students. The total number of studen

nirvana33 [79]

R - Right Handed
L - Left Handed

R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids)
9L + L = 30 ( since total number of people in class is 30)
10L = 30
( Divide by 10 both sides )
L = 3

so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)

Find the exact angular velocity in radians per hour wind W= 4.1 rpm

nataly862011 [7]

Answer:

1545.66 rad/h

Step-by-step explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

$4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h$

So, the required angular velocity is 1545.66 rad/h.
