Achemist is mixing a 30% salt solution with a 20% salt solution to make 35 l of a new solution that will contain 25% salt. how much of the 30% solution should the chemist use?

17.5 L

Step-by-step explanation:

x L  of  30% solution , has 0.30x salt

35 L of 25 % solution, has (0.25*35) salt

(35 - x)L  20% solution, has 0.20*(35 - x) salt

Mass of salt before mixing = mass of salt after mixing

0.3x + 0.2(35 - x) = 0.25* 35

0.3 x + 7 - 0.2x = 8.75

0.1x = 8.75 -7

0.1x = 1.75

x = 17.5 L

answer: no

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
