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 1

w1 • d1 = w2 • d2

We need to isolate d2 on one side of the equal sign. So we need to get rid of any terms next to it by using inverse operations. The term next to d2 in this equation is w2. It is being multiplied by d2. So, to cancel it out, we need to divide both sides by w2.

\[\frac{ w1 \times d1 }{ w2 } = d2\]

Answer 2

ok....is the last part the answer
