Suppose that a chemist is mixing two acid solutions, one of 30% concentration and the other of 40% concentration. Which of the following concentrations could not be obtained? 32%, 34%, 38%, 42%

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

it would be 198 people.

hope it
