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
`(d)/(r)=t`

8.

For this, divide both sides by nR and your answer will be
`(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
`(1000C)/(tc)=W`
