<em>To solve for a variable, you just need to isolate the variable to one side.</em>

<h3>7.</h3>

For this, just divide both sides by r and <u>your answer will be \frac{d}{r}=t</u>

<h3>8.</h3>

For this, divide both sides by nR and <u>your answer will be \frac{PV}{nR}=T</u>

<h3>9.</h3>

Firstly, multiply both sides by T: AT=FV-OV

Next, subtract FV on both sides of the equation: AT-FV=-OV

Lastly, multiply both sides by -1, and <u>your answer will be -AT+FV=OV</u>

<h3>10.</h3>

Firstly, multiply both sides by 1000: 1000C=Wtc

Lastly, divide both sides by tc and <u>your answer will be \frac{1000C}{tc}=W</u>

How to do percentages ?
Rus_ich [418]
Say you're trying to figure out what percentage 3 is of 15.

3/15 = x/100

You would cross multiply so..

3(100) = 15x

Then simplify.

300 = 15x

300/15 = 15x/15

20 = x

Therefore, 3 is 20% of 15.
