anonymous one year ago 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.

1. welshfella

w1 . d1 = w2 . d2 divide both sides by w2 and you have it.

2. anonymous

Oh ok that's not that hard at all so u understand when one thing multiplies on one side it divides on other

3. anonymous

So what they are saying make d2 the subject

4. anonymous

Which means d2 must be left alone in one side so you w2 is multiplying by d2 just divide it in the other side

5. anonymous

w1 x d1 = w2 x d2 1 = 4 ?? im soz im confused by this

6. anonymous

Where did u get 1=4

7. anonymous

well multiplying idek how ;-;

8. Goose.

Do you have any numbers to plug in?

9. anonymous

No you won't get 1=4 you will get d2= ( w1 times d1)/ w2

10. anonymous

There are no numbers in question which u need to plug in

11. welshfella

you are give no values yor answer will be a formula with d2 as the subject

12. imqwerty

$w _{1}\times d _{1}=w _{2}\times d _{2}$divide both sides by w2 u get-$\frac{ (w _{1} \times d _{1}) }{ w _{2} }=d _{2}$

13. welshfella

exactly - that's what i said to do in my first post

14. anonymous

so then its just w2 = d2 thats the final answer

15. anonymous

?*

16. welshfella

No the answer is the formula that imqwerty gave in his post

18. welshfella

that's it

19. anonymous

oh ok thx soz i just suck at math su thanks XD
