Helena has saved $595 to put toward snowboarding equipment and lift tickets at the hill. each lift ticket costs $35. if she wants to have more than $420 of her savings left to spend on equipment, which inequality represents the number of lift tickets she can buy? a. x< 5 b. x=4 c. x> 7 d. x=7

595 - 35·x > 420 --> x < 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

no this is a nonlinear negative
