Question

Hi can you help me please?)

Answer 1

To solve for a variable, you just need to isolate the variable to one side.

7.

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

8.

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

9.

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 your answer will be $-AT+FV=OV$

10.

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

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