Answer:
A Matter is not created or destroyed and the same amount of mass remains
Explanation:
In a chemical reaction, according to the law of conservation of matter, "matter is neither created nor destroyed and the same amount of mass remains in such a process".
- New kinds of products are formed in a chemical reaction because they undergo chemical changes.
- The chemical changes results in energy changes and formation of new kinds of substances.
- Based on the law of conservation of matter, mass is constant.
- Mass is not lost or gained.

<em>x < 4</em>
Explanation:
<u>Inequalities</u>
The inequalities relate expressions using signs different from the equal sign, like "<" or "<" among others.
They can be treated as a normal equation but in case of directional relationals, care must be taken when multiplying or dividing by negative numbers.
The inequality given in the question is
3x - 4 > 4x - 8
Subtracting 3x in both sides
3x - 4 -3x > 4x - 8 -3x
Simplifying
-4 > x - 8
Adding 8
-4 + 8 > x - 8 + 8
Simplifying
4 > x
The solution comes by flipping both sides and the inequality sign
x < 4
