most likely it is the 3rd one
Answer:
![\sf x = \dfrac{n - 2mp}{2m}](https://tex.z-dn.net/?f=%5Csf%20x%20%3D%20%5Cdfrac%7Bn%20-%202mp%7D%7B2m%7D)
Step-by-step explanation:
![\sf 3m = m + \dfrac{n}{p + x}\\](https://tex.z-dn.net/?f=%5Csf%203m%20%3D%20m%20%2B%20%5Cdfrac%7Bn%7D%7Bp%20%2B%20x%7D%5C%5C)
![\sf 3m - m = \dfrac{n}{p +x}](https://tex.z-dn.net/?f=%5Csf%203m%20-%20m%20%3D%20%5Cdfrac%7Bn%7D%7Bp%20%2Bx%7D)
![\sf 2m = \dfrac{n}{p +x}](https://tex.z-dn.net/?f=%5Csf%202m%20%3D%20%5Cdfrac%7Bn%7D%7Bp%20%2Bx%7D)
Now cross multiply,
2m*(p +x) = n
To open the parenthesis, multiply 2m by p and x.
2mp + 2mx = n
Isolate the term with variable 'x'
2mx = n - 2mp
Now, isolate 'x', by dividing both sides by 2m
Well I'd assume you mean this:
If I choose 20
20+5x(-4)-3
5x-4 =-20
20 +(-20) - 3
0-3 is -3
and so on
Answer:
45
Step-by-step explanation:
1 minute = 8 revolutions
x minutes= 360 revolutions
Divide 360 by 8
45
The wheel will make 360 revolutions in 45 minutes
Check your work:
If 45 minutes = 360 revolutions, and the wheel revolves 8 times per 1 minute, 8 revolutions x 45 minutes should equal 360 revolutions.
