A is five less than four times a number, which is represented by letters?
It is helpful for the responder to give an accurate answer

If this number is replaced by X, then:
A=4X-5
4X=A+5
X=(A+5)/4

If the letter A is a positive number, what number does - a represent?

A is a negative number. If the left side of the origin on a number axis is a negative number, then - A is the a number on the left side of the number axis, and the right side of the number axis is a positive number, then a is the a number on the right side of the number axis

We use the letter A to represent a rational number, and try to judge whether the following statements are correct. If not, please give counter examples. (1) a must be a positive number, - a must be a negative number; (2) if a is zero, then - A is a negative number; (3) if - A is a positive number, then a must be a non positive number

(1) Error, a = - 3, - a = 3; (2) error. A = 0, - a = 0; (3) error. Non positive numbers include zero and negative numbers

Please judge whether the following statements are correct. If not, please give counter examples
Homogeneous, stable liquid is solution & nbsp;
The solute in the solution must be a solid
The solvent in the solution must be water
There is only one solute in the solution

Definition of solution: a solution is a homogeneous and stable mixture of at least two substances. The dispersed substance (solute) is dispersed in another substance (solvent) with molecules or smaller particles
According to the definition and explanation, it can be judged that:
The homogeneous and stable liquid in the first sentence is wrong. The solution must be a mixture
The solute can be any of the three forms of gas, liquid and solid
In the third sentence, the solvent "must be water" is wrong. Other liquids can also be used as solvents
There is only one solute in the fourth sentence. It is wrong to say "at least two" in the definition, that is, two or more solutes can be used. Counter example: in chemical experiments, when two solutions are mixed, there is no chemical reaction, such as the mixed solution obtained by mixing sodium chloride and dilute sulfuric acid

Judge whether the following statements are correct. If so, please give reasons. If not, please give counter examples
Two groups of quadrilateral whose opposite sides are equal must be planar

Two groups of quadrilateral whose opposite sides are equal must be plane figure, which is incorrect
If the diamond is turned to an arbitrary angle along a diagonal line, two groups of unequal edges with equal opposite sides can be obtained
A quadrilateral in a plane

Judge whether the following statement is correct or wrong. If it is wrong, please give a counter example
The sum, difference, product and quotient of two irrational numbers are still irrational

The sum of two irrational numbers is also irrational, because irrational numbers can't be written as fractions, and the sum of two irrational numbers that can't be written as fractions can't be written as fractions, so it's also irrational
The difference between two irrational numbers is irrational in general. But when the two irrational numbers are the same, the difference is zero. Of course, it is rational
If the root 2 times the root 2 equals 2, the result is a rational number
Root 8 divided by root 2 equals 2, the result is a rational number

Combined with the operation of specific numbers, through the induction of special cases, and then judge the right and wrong of the following statements, think it is right, explain the reason; think it is wrong, give counter examples
(1) No number is equal to her opposite
(2) The same even power of two opposite numbers is equal
(3) If a is greater than B, then the reciprocal of a is less than the reciprocal of B

Analysis: (1) any number is not equal to her opposite number. This proposition is wrong. The counterexample is: the opposite number of 0 is equal to her own (2) the same even power of two numbers which are opposite to each other is equal. This proposition is correct. If a and B are opposite to each other, then a = - B, then a & sup2; = B & sup2;, and the even power is an integral multiple of the square
