A saline solution was placed under a heat lamp in an experiment. At 10:00 a. M., it had a 21% salt concentration. At 3:00 p. M., the salt concentration increased to 46% due to evaporation. By what percent did the salt concentration increase between 10:00 a. M. And 3:00 p. M.?

easy math just plug in a and b

step-by-step explanation:

pls ask

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!
