An experienced computer technician can set up a network in 12 hours. it would take an intern 20 hours to set up the same network. if they work together, how long will it take to set up the network

How do i do this? i don’t understand

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5
