equations with variables on both sides problems

Which of the following is the variable equation for 'Perimeter (P) is 4 times the side'? => P = 4 - s or P = 4 ÷ s or P = 4 + s or P = 4 × s..

Linear equations in two variables - A Linear equation is a first degree algebraic expression with one,two or more variables equated to a constant. Graphically a linear equation with one or two variables is a straight line whereas..

Variable - Quantities such as height, weight, age, amount can have several different values. Quantities which can assume different numerical values are called variables. Variables are of two types: (a) Continuous (b) Discre..

Quantities such as height, weight, age, amount can have several different values. Quantities which can assume different numerical values are called variables. Variables are of two types: (a) Continuous (b) Discret..

The perimeter of a square is 4 × side. Which of the following is true for the data? => Perimeter dependent variable or Insufficient data or Perimeter is independent variable or Side is dependent variable..

A measurable property required to describe the state of a system is called state variable. For example, temperature (T), pressure (P), volume (V) etc. are the state variables. For any system, a certain minimum number of variables are sufficient to define its state, as..

A continuous variable can assume all values within a certain range, e.g., height, weight and age of persons are examples of continuous variables..

Angle, specific gravity, strain etc., do not have any dimensions and any constant value and hence, are variables..

Consider an example: The number of pupils in a class can be 30, 34, 40. But it cannot be 30.2, 35.1, because number of pupils can be expressed only as a whole number. Such numerical as number of children, trees, sheep are called discrete variables..

A discrete variable can assume only integral values which can be counted. Number of pupils in a school, persons working in a factory are examples of discrete variables. A list of some important terms is given below. (i) ungrouped data (ii) tabulation of data (iii) range (iv) fr..
