(15 pt.) linda had been collecting stamps for 5 weeks and had 25 stamps in her stamp book. her book holds 64 stamps. she then began purchasing 3 stamps each week. what was the total number of weeks that it took linda to fill her stamp book? show your work. (hint: you will need to setup an equation to solve this problem.)

Do not comment if you aren’t going to . create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

Given a circle with measures of (c, d, and r) and a circle with measures of (c', d', and r'), what is d if c c' = 12 and d' = 0.50? a) 3 b) 6 c) 12 d) 24

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).
