Give a box of apples to several children. If each child is given 5 apples, there are 12 apples left. If each child is given 8 apples, the last child gets 8 apples, but there are less than 8 apples. Find the number of children and the number of apples in this box
If there are x children, then the number of apples is (5x + 12). According to the meaning of the question, we get: 0 < 8x - (5x + 12) < 8, which can be changed into: 3x − 12 > 03x − 12 < 8. The solution is: 4 < x < 203, ∵ x is a positive integer, ∵ x takes 5 or 6, when x = 5, 5x + 12 = 37; when x = 6, 5x + 12 = 42, ∵ there are two situations to meet the meaning of the question: ① there are 37 apples in this box, children have 5 digits; ② there are 42 apples in this box, children have 5 digits There are six friends

It is known that in ladder ABCD, AD / / BC, point E is on AB, point F is on AC, and ad = a, BC = B Ask for: (1) Let E and f be the midpoint of AB and DC respectively, and verify: EF / / BC, and EF = half (a + b) (2) If: AE than EB = DF than FC = m than N, judge whether EF and BC are parallel, and use the algebraic expression of a, B, m, n to express EF, and prove. This problem can still be imagined without a picture, that is, an ordinary trapezoid has made a median line. The essence is to prove that the trapezoid median line is one-half of the trapezoid (upper bottom + lower bottom) and parallel to the bottom`
