Question

I need help ASAP!
I'm confused can someone explain this to me. ( Thank you )

Answer 1

7.) Solve for w (isolate w)

P = 2L + 2W Subtract 2L on both sides

P - 2L = 2W Divide 2 on both sides

`(P-2L)/(2)=W` You can simplify it to this(but idk if you have to):

`(P)/(2) -L=W`

You could have also done it this way:

P = 2L + 2W Factor out 2

P = 2(L + W) Divide 2 on both sides

`(P)/(2) =L+W` Subtract L on both sides

`(P)/(2)-L=W`

8.) Solve for t

D = rt Divide r on both sides

`(D)/(r) =t`

9.) Solve for C

`F=(9)/(5)C +32` Subtract 32 on both sides

`F-32 = (9)/(5) C` Multiply 5/9 on both sides to get rid of 9/5

`(5)/(9)(F - 32)=((5)/(9))(9)/(5)C`

`(5(F-32))/(9)=C`

`(5F - 160)/(9)=C`
