1. Чему равен: $x = 2 * "15%" - 18 + "$23";
Ответ: 12
Обоснование: Здесь использутся математические вычисления. А значит, 15% - приводятся к числу 30, а "$23" вообще не может быть вычислено и является NULL для матвечислений

2. Чему будет равен $z = (empty($x) && isset($y)) ? 10:20,  если:
  a) $x = 0; $y = 0;
  //карман $x есть , в кармане пусто, занчит true
  //карман $y есть, значит true;
  Ответ: 10
