In a school zone, 29 teacher positions need to be hired for the following areas: 13 of mathematics, 13 of physics and 15 of systems. By covering the positions require 6 teachers to teach mathematics and physics, 4 to teach physics and systems and 5 mathematics and systems. Using a Venn diagram determine: a) How many do you need to teach the 3 areas? b) How many do you need to teach mathematics only? c) How many do you need to teach mathematics and systems, but not physics?
