The difference of vidya’s height and 15 is 74?

 V - 15 = 74;     V = 89

Step-by-step explanation:

"difference" means subtraction

"is" means equals

Vidya's height minus 15 is 74

                V         -      15  =  74

To solve, add 15 to both sides: V - 15 + 15 = 74 + 15

                                                                 V =    89

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
