Question: How do you write : Five times the sum of a number and one ?...
How do you write : Five times the sum of a number and one ?
Solution
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 getx+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 24,9are the constants
2.2x+98+78yis 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.
