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.

what have you got so far?

anonymous · Answer

i have got the numbers all written down and the things they equal... I also have made the multiplication division by x1 * d1 over w2

jim_thompson5910 · Answer

does it give you a diagram or something?

jim_thompson5910 · Answer

the numbers are missing

jim_thompson5910 · Answer

oh they just want you to solve for d2 only?

anonymous · Answer

how do i figure out the numbers? no it doesn't

anonymous · Answer

im in the literal equations lesson

jim_thompson5910 · Answer

I think they just want you to solve for d2

jim_thompson5910 · Answer

to do that, we simply divide both sides by w2 to isolate d2


$$\Large w_{1}*d_{1} = w_{2}*d_{2}$$

$$\Large \frac{w_{1}*d_{1}}{w_{2}} = \frac{w_{2}*d_{2}}{w_{2}}$$

$$\Large \frac{w_{1}*d_{1}}{w_{2}} = d_{2}$$

$$\Large d_{2} = \frac{w_{1}*d_{1}}{w_{2}}$$

anonymous · Answer

yes thats what i believe well they say they want to see your rewrite formula for the solving of d2

jim_thompson5910 · Answer

yeah basically get d2 on one side all by itself

anonymous · Answer

then the basic formula is meaning isolate the variable sort of like d=r*t

jim_thompson5910 · Answer

yeah d is isolated

anonymous · Answer

ok so the general formula is ?

jim_thompson5910 · Answer

I just wrote it above

jim_thompson5910 · Answer

when I solved for d2

i got it thanks :D
