Ib math proof
Webb19 maj 2024 · Proof: Let a, b, c ∈ Z, such that a ≡ b(modn) and b ≡ c(modn). Then a = b + kn, k ∈ Z and b = c + hn, h ∈ Z. We shall show that a ≡ c(modn). Consider a = b + kn = (c + hn) + kn = c + (hn + kn) = c + (h + k)n, h + k ∈ Z. Hence a ≡ c(modn). Thus congruence modulo n is transitive. Theorem 5: The relation " ≡ " over Z is an equivalence relation. Webbccss.math.content.hsg.srt.b.4 Prove theorems about triangles.

In order to prove q → p, suppose 5 r − 1 2 r is rational, so 5 r − 1 2 r = a b for some non-zero integer a, b. So, isolating for r would get: r = b 5 b − 2 a. So here's my question:
