Question

I need help it says solve for w when the formula is p=4+2w I dont know what to do with the p

Answer 1

first, get the w term by itself. So move 4 over to the left hand side. Do you know how to do this?

Answer 2

that does not explain the steps of the problem....

Answer 3

what I did I divide 2 on both sides and my answer I got is w=4/2

Answer 4

the first step: when you have p=4+2w, you first move the 4 over to the left hand side. you do this by subtracting. So your equation become p-4=2w.
The next step to getting w by itself is to divide both sides by 2.
So we end up with p/2 - 2=w.

Answer 5

Does this make sense?

Answer 6

yes know it does thank you

Answer 7

you're welcome!

Answer 8

could you help me in 2 more problems

Answer 9

yeah sure

Answer 10

ok a=s squared solve for s
and the other ones is 3.14r squared solve for r

Answer 11

s = \[\sqrt{a}\]

this is because \[\sqrt{s^{2}}\]=s, and what you do to one side you must do to the other.

Answer 12

and the other question is just \[3.14r^{2}\]? is it set equal to anything?

Answer 13

no it just says a=3.14r squared

Answer 14

ok, so first divide both sides by 3.14

Answer 15

then you're left with \[\frac{ a }{ 3.14 } = ^{2}\]

Answer 16

\[r^{2} *\]

Answer 17

so then we do the same thing as we did in the last problem...what you do to one side you must do to the other

Answer 18

so \[r = \sqrt{\frac{ a }{ 3.14 }}\]

Answer 19

ok thank you so munch you made it easier to me to understand I wish you were my teacher instead thank you so much

Answer 20

Aw well I'm glad I helped!! let me know if you have any other questions
