2007年初一数学期中模拟考试卷（In the first day of 2007, the math exam was simulated）

2007年初一数学期中模拟考试卷（In the first day of 2007, the math exam was simulated） In early 2007 mid-term exam mathematical simulation (time: 100 minutes, 100 points) Class: Name: performance: Fill in the blanks (2 points per day, a total of 24 points) In 1, 0, 1, 1, 2, EMBED solutions of Equation.3 equations. 2, or fill in the blank: a b, is A1 B1. 3, equation 2x = 4 solution. 4, by 3x - algebra y+6 = 0 obtained with x y for y =. 5, if a x equation Ax6 = 0 solutions for x = 3, a =. If the number is 6, and 12, the difference is 4, then the two number respectively. 7, if the EMBED Equation.3 is a EMBED Equation.3 equation, a =. In 8, the solution of inequality represented by Y1 = 9, y2 = 3x2 known, 4x, if Y1 is less than Y2, X. 10, EMBED Equation.3 inequalities and the solution set is _________. 11, 1000 yuan in the bank for 4 years, the annual interest rate of 5%, after the expiration of 20% of the interest tax deduction, the total interest can be obtained for V. s. yuan. 12, Xiao Ming to 1350 meters away from the cinema, 5 minutes walk 250 meters, according to this calculation, arrived at the cinema also need how many minutes? A need for X minutes can be arrived at the cinema, column equation. Two, choose (every day 3 points, a total of 18 points) 13, the following equation step, the right is () A, -12x = 6 EMBED Equation.3 B, EMBED Equation.3 EMBED Equation.3 C EMBED, Equation.3 x D, 2x-1=7x+6 2x-7x=6+1 = 1 14, if the equation 3x1 = 5, then the algebraic 6x4 value is () A, 8; B, 10; C, 2; D, 6. 15, Zhao to the denomination is 20 yuan RMB change, now only 5 yuan and 1 yuan two yuan denomination available, so he has several ways to change (different) A, 4; B, 5; C, 6; D, 7. 16, integer inequalities EMBED solution of Equation.DSMT4 is () A, 3; B, 4; C, 5; D, 6; 17, some students dormitory, every 4 people more than 20 people, every 8 people have a non empty dormitory is also dissatisfied with the () A, 5 B, 6 C, 7 D, 8 18, with 500 yuan of money to his store to buy a recorder
