Yes, the solution to a two-variable system is the point where the equations of the lines representing the system intersect on a graph. This point represents the values of the variables that satisfy both equations simultaneously.
Equations are mathematical statements that show the equality of two expressions, typically separated by an equal sign. They are used to solve for unknown variables by manipulating the expressions to find a solution that satisfies the equation. Equations play a fundamental role in mathematics and are used in various fields to describe relationships between quantities.
If the two solids are both metals, then the result is an alloy. However, cast iron for example is a mixture of carbon and iron, so technically it may be an alloy. But a car tyre is made of rubber, chalk, sulphur, rosin, etc. I guess the only answer for this is a mixture. If the two metals are in fluid solution, then it is a mixture.
The concentration of a solution of two or more liquids is expressed as a percentage by dividing the amount of solute by the total amount of solution (solute + solvent) and multiplying by 100.
A solution refers to a homogeneous mixture composed of two or more substances. In a solution, the solute is dissolved in the solvent, resulting in a single phase with uniform composition. Solutions can be in various states, such as solid, liquid, or gas.
