1..Danny is 60lbs, Maria is 40lbs, both are balanced on seesaw that is 10ft. If the fulcrum is x ft away from Danny, what is x? Danny.........f...........Maria Distance from Danny to f = x. Distance from Maria to f = 10 - x. Equation 60x= 40(10 - x) You say?. 2. John weighs 80 pounds and sits 4 feet from the fulcrum of a seesaw. If Sally weighs 100 pounds and sits on the other side, how far from the fulcrum must she sit to have the seesaw balance? John........f...........Sally Distance from John to f = 4 feet. Distance from Sally to f = x. Equation 80(4) = 100x Yes?
