Question

Two boys want to use a seesaw and they need to move the seesaw so that their weights will balance out. The formula is given by w1 • d1 = w2 • d2 where w1 = weight of the first boy, d1 = distance of the first boy from the fulcrum, w2 = weight of the second boy, and d2 = distance of the second boy from the fulcrum. Rewrite the formula to solve for d2. Show all steps in your work

Answer 2

Oh I did this a week or two ago.

Answer 3

To solve for d2 get d2 by itself on one side of the equal sign.

Answer 4

We can do that by dividing w2 to both sides:

So we have:

w1 x d1/w2 = d2

So:

d2 = w1 x d1/w2 is your equation.

Answer 5

I wish my algebra was this easy :(

Answer 6

Soo.. d2= w1 x d1/w2 is the equation... Now thats all?

Answer 7

I thought you did this like a week ago? haha

Answer 8

Yes that's your equation that's all you have to do . . .

Answer 9

A few weeks ago actually . . . I'm deeper into the course now . . .

Answer 10

Oh god.. you got me scared .. lol

Answer 11

??? How??

Answer 12

because math is my week spot.. & goin in deep its DEEP

Answer 13

Will you help me with another plz? @greenlegodude57

Answer 14

Um, okay . . .

Answer 15

The area of this figure can be found by the formula A = (wh) + 0.5(bh). If Marcie wants the total area to be larger than a specified value, she can use the formula A > (wh)+ 0.5(bh). Rewrite this formula to solve for b. Show all steps in your work.

Answer 16

Lets see, um, A > (wh) + 1/2(bh)
2A > (wh) + (bh)
2A - (wh) > (bh)
2A - wh/h > b

Answer 17

So your equation is b < 2A - wh/h

Answer 18

Your awesome!! Btw how do I give you a medal? I just never realized how to give them out lol
