Let x = {a, b,c, d,e) and t = {0,{,,c,,c, d,e),x) (a). show that t is a topology on x. (b). what are the closed sets in t (c). what are the closures and interiors of (a), (b} as well as their boundaries. (d). give the closure of fa, bj. what can be deduced from that? (e). give the neighborhoods of c and d. (f). is t hausdorff.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
