Question

2.1(s + 1) − 1.41 = 6.99 what is the value of s

Answer 1

Answer:

The required value of $s$ is $3$.

Step-by-step explanation:

Given : $2.1(s+1)-1.41=6.99$

To find : The value of $x$.

Solution :

• The given expression is,

            $2.1(s+1)-1.41=6.99$

• We have to find the value of $s$.
• In order to find the value of $s$, we have to solve the given expression using BODMAS rule.
• It states that, while solving any algebraic expression, we should first solve the B-Brackets, O-Order, D-Division, M-Multiplication, A-Addition and S-Subtraction.
• By using the above rule, on solving given expression, we get

     ∴ $2.1(s+1)-1.41=6.99$

     ∴ $2.1s+2.1-1.41=6.99$

            ∴  $2.1s+0.69=6.99$

                      ∴ $2.1s=6.99-0.69$

                      ∴ $2.1s=6.3$

                          ∴ $s=\frac{6.3}{2.1}$

                          ∴ $s=3$

• ∴ The required value of $s$ is $3$.

Answer 2

The given equation is 2.1(s + 1) 1.41 = 6.99,

According to the data provided in the question.

We have to find the value of s.

To find the value, we must simplify the given equation.

As a result of simplifying the equation above, we arrive at

$2.1(s + 1)- 1.41 = 6.99\\2.1s+2.1-1.41=6.99\\2.1s+0.69=6.99$

To solve the equation further moving constant term to right hand side we get,

$2.1s=6.99-0.69\\2.1s=6.3\\s=\frac{6.3}{2.1} \\s=3$

Therefore the obtained value of s 3.
