Please help m A lemonade is made by mixing flavored powder, x, with water, w. The chart below shows some measurements that can be used to make different amounts of lemonade.

1. Write an equation that represents this relationship.

2. What is the constant of proportionality, and what does it mean in this example?

bro wher is the measurements

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
