Question

How do you write : Five times the sum of a number and one ?

Answer 1

Hint:In order to determine the mathematical expression from the above statement ,first we have to understand the statement carefully. Split the statement into two parts ,”Sum of a number and one”, let the number be x and when we sum 1 with the x we get$x + 1$.Now the remaining part of the statement says the “five times” of what we have got till now .So multiplying 5 with $x + 1$ will lead to our required expression.

Complete step by step solution:
In order to write any mathematical expression from some words and figures ,we must first find the relationship and the quantities specified .

Here in this question the relation between a number let suppose x is that it's saying that something number x in the form of variable taken here as per question. So sum of a number then means addition with the number x and one.

So we are replacing the sum of the number and one word from the sentence with the addition symbol (x+1) replacing sum of a number with addition $' + '$ symbol and writing ‘1’ as it is.

$ = x + 1$

And then a question arises how many times is the sum of a number ,so we are given five times.

So , now our question has become perfect to say that Five times the sum of a number and one replacing sum of a number and one with addition$' + '$ symbol and ‘1’ itself.

Note: 1.Mathematical equation : A Mathematical equation can be defined as the mathematical statement which contains an equal symbol $ = $ in between two algebraic expressions that share the same value.

A algebraic expression can contain any number of variables generally we take 2-3 variables
Let assume a expression
$5x + 9 = 24$

It is a mathematical equation having LHS (Left-Hand-Side) equal to RHS (Right-Hand-Side)
Where $x$ is the variable 5 is the coefficient of variable $x$ And $24,9$are the constants

2.$2x + 98 + 78y$is not a mathematical equation because it does not contain equality $ = $ symbol . It is only a mathematical expression.

3. Read the statement carefully in order to convert them into mathematical expressions.
