BEAT THE TESTI 1. Which of the following equations have the correct
solutions Select all that apply,
2x + 5 = 19; X = 7
3+x+2-x=16; x =3
x+2/5=2; x = 8
6 = 2x -8; x = 7
14 =1/3x+5; x = 18

Step-by-step explanation:

2x + 5 = 19; X = 7: Correct

2(7) + 5 = 19

14+5=19

3+x+2-x=16; x=3 : Incorrect

3+3+2-3=16

6+2-3=16

7-3=16

4=16

x+2/5=2; x = 8: incorrect

8+2/5=2

x= 8/5

6 = 2x -8; x = 7: correct

6 = 2(7) -8

6 = 14-8

14 =1/3x+5; x = 18: Incorrect

14 = 18/3+5

14 = 6+5

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?
