Noah is solving the inequality 7x + 5 > 2x + 35. First, he solves the equation 7x + 5 = 2x + 35 and gets x = 6. How does the solution to the equation 7x + 5 = 2x + 35 help Noah solve the inequality 7x + 5 > 2x + 35? Explain your reasoning.

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.
