Asegment is 3 units long. it is divided into 9 parts. what fraction of a unit are 2 parts of the segment?

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

Find the value of x. give reasons to justify your solutions! l, m ∈ kn

Ineed the solution to this problem and the steps.
