Last night julie’s pet hamster zoe kept julie awake for at least an hour running on her exercise wheel and scratching at the corner of her cage so he ran on the wheel at least twice as long as she scratched at the corners of her cage and she spent more than a quarter hour running on her wheel which system of inequalities represents a time so we kept julie awake last night if x is the number of hours that we spent running on her will and why is the number of hours spent scratching her cage
