one balloon can lift a basket containing items weighing at most 80 kg. two such balloons can lift the same basket containing items weighing at most 180 kg. what is the weight of basket?
Let X be the mass of a basket. Then one sphere can lift 80+X,two spheres will lift one basket and 180 kilograms. And if each sphere lifts a basket and still something that is, they will lift 2 baskets and 160 kilograms. Let's work out the equation for two spheres. 2X + 160 = X+180, and from here we will receive the mass ofa basket = 20
