\(a=\frac{v}{t}\) solve for *t*

\(A=\pi r^2\) solve for *r*

*\(P=I^2R\)* solve for *I*

a = v/t Multiply both sides of the equation by 't

at = v Divide both sides by 'a'

t = v/a

A=pi r^2 Divide both sides by pi

A/pi = r^2 Sqrt both sides

sqrt(A/pi) = r Do you see how it is done? Can you do the third one?

I think you are correct....can honestly say I have not found ONE SINGLE thing in the 'update' that was a good change.

Lol how about the hearts for points EP?

You gotta at least like them a little x)

Nope. Posted earlier that I thought the hearts were cheesy and the symbol should be something math-related like # or the pi symbol ! Just not feelin' the heart thingie ....

All "solve for" means is get the variable by itself on one side of the equal sign.

\(a=\frac{v}{t}\)

Multiply both sides of the equation by t.

\(ta=v\)

Divide both sides of the equation by a.

\(t=\frac{v}{a}\)

Hey! time = velocity / acceleration

\(A = \pi r^2\)

Divide both sides of the equation by pi.

\(\frac{A}{\pi} = r^2\)

Take the + square root of both sides.

\(\sqrt{\frac{A}{\pi}} = r\)

radius = the square root of (area / pi)

The third one is exactly the same as the second one just with different letters.
