I've never been good at math he told he loves but he keeps cheating on me, so it ain't adding up sis

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

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
