If a word problem states "no more than", the corresponding inequality sign is less than or equal to (≤).
For example, if x is no more than than 4, then:
x ≤ 4.
If an inequality states "no more than," you would use the less than or equal to sign (≤). This indicates that the value can be either less than or equal to a specified number. For example, if the inequality is expressing that a variable ( x ) is no more than 10, it would be written as ( x ≤ 10 ).
Nod your head no .
A more formal name is the strict inequality sign.
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.
The multiplication property of equality states that if you multiply both sides of an equation by the same non-zero number, the two sides remain equal. In contrast, the multiplication property of inequality states that if you multiply both sides of an inequality by a positive number, the inequality remains unchanged, but if you multiply by a negative number, the inequality sign must be flipped. Thus, while equality preserves its form, inequality requires careful handling based on the sign of the multiplier.

When you divide both sides of an inequality by a negative number, the inequality sign flips.
"x281" is an expression, not an inequality. An inequality is supposed to have an inequality sign, such as "<" or ">".
It's the "less than" sign [ < ] above the "equals" sign [ = ].≤When you see it, you read it " ... less than or equal to ... ". That's the same as " ... no more than ... "
There is no inequality since there is no inequality sign.

No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
