2. In the triangle ABC, AB=AC, and the circumference is 16 cm. The middle line BD of the AC side divides the triangle ABC into two triangles with a circumference difference of 2 cm, and finds the length of the triangle ABC.
3. If x=-3 and y=-2, it is the solution of binary linear equations AX+CY = 1 and CX-by = 2, and the value of 3/2a+2/3b+5/6 is found. 4. Party A and Party B have the same solution to the equation set 1AX+5Y = 65436. The solution of the equations is x=-3 y=- 1, b misreads b in ②, and the solution of the equations is x=5 y=4. Try a word 5 of 2005+(-110b) 2006. As shown in the figure, CA, BA = AC, 00b.
6. The intersection of the image with y =-x+m and the X axis is (-2,0). What is its intersection with the y axis? 7. 1. Given 2x+4/x (x-1) (x+2) = a/x+b/x-1+c/x+2 (where a, b and c are constants), find a, b and c.
8. 1 The total number of people in workshop and workshop 2 is 150. Five people from workshop 1 were put into workshop 2, and the number of people in both workshops was equal. Find out the number of people in the workshop. 9. The sum of two digits and ten digits is 10. If the positions of one digit and ten digits are exchanged, the two digits are larger than the original 18. Find the original two digits.
10.3. There are 32 workers in a factory 1 workshop, 62 workers in workshop 2, and 98 workers in two workshops. How to match it so that the number of people in workshop 2 is three times that of 1 workshop?
