e = 1/2 mv ^2
Times 2 for both sides.
2e = mv^2
And this is because you are trying to find the formula when solved for v.
And I can help you find that formula which is:
mv^2 = 2e
v^2 = 2e/m
v = √(2e/m)

forgive me if im wrong but I'm sure it's that
<span>A = 157, B = 23
The definition of supplementary angles is that they add up to 180 degrees. So A+B = 180. And A = 7B - 4.
So write down the formula
A + B = 180
Substitute the formula for A in terms of B
7B - 4 + B = 180
Combine terms
8B - 4 = 180
Add 4 to both sides
8B = 184
Divide both sides by 8
B = 23
Now calculate A in terms of B
A = 7B - 4
A = 7 * 23 - 4 = 161 - 4 = 157
Verify that A and B add up to 180
157 + 23 = 180</span>
