Answer:
<h2>u = 2T - v</h2>

Cross multiply
We have
2T = u + v
u + v = 2T
Move v to the right side of the equation to make u stand alone
We have the final answer as
<h3>u = 2T - v</h3>
Hope this helps you
Answer:
a)$4,238.50
b)$392
c)$3814.65
Step-by-step explanation:
a) 3920*0.08125=318.5
318.5+3920=4238.50
b)3920*0.1=392
c)3920-392=3528
3528*0.08125=286.65
3528+286.65=3814.65
Question:
Solution:
Let the following equation:
![\sqrt[]{12-x}=\text{ x}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B12-x%7D%3D%5Ctext%7B%20x%7D)
this is equivalent to:
![(\sqrt[]{12-x})^2=x^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B%5D%7B12-x%7D%29%5E2%3Dx%5E2)
this is equivalent to:

this is equivalent to:

thus, we can conclude that
x= 3.
Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
The answer to this is a=3
