43. A) I think its 2 pairs of shoe and one shoe is left because the guy either lost it, or just has an extra shoe. 43. B) If one of the pairs is missing a shoe then there is 4 shoes because there was already one shoe missing a pair but it's still there so if one pair is missing one completely like, it's not there then there's five. 44. 4xy²+3x-5. 45. I am not good at this. But I think: Sally has x beans she gave 8 to Marcus. How many does Sally have now? 46. Yes because whatever y is times one is still going to be y and according to pemdas its multiplication the addition so therefore it would me 1xy then it would be yx4 and it would still be the same answer.
