Question

if you subtract 5 from a number and divide the result by 2 you get 10 what is the number​

Answer 1

Answer:

25 is the required number.

Step-by-step explanation:

Step 1 of 2

Let the required number be $x$.

According to the question,

Subtract the number 5 from the required number, i.e.,

⇒ x - 5

Now, divide the obtained result by the number 2 to get 10, i.e.,

⇒ (x - 5)/2 = 10

⇒ $\frac{x-5}{2}=10$

Step 2 of 2

Solve for x.

Multiply both the sides by the number 2 as follows:

⇒ $2\times\left(\frac{x-5}{2}\right) = 10 \times 2$

⇒ x - 5 = 20

Adding the number 5 both the sides as follows:

⇒ x - 5 + 5 = 20 + 5

⇒ x = 25

Therefore, the required number is 25.

What is the definition of arithmetic operation?

Combining operands with a single arithmetic operator specifies an arithmetic operation. Additionally, addition, subtraction, multiplication, and division can be used to define arithmetic operations.
let the number be $x$ .

According to the questions we get

$\frac{x-5}{2}=10\\\Rightarrow x-5=10 \times 2\\\Rightarrow x-5=20\\\Rightarrow x=20+5\\\Rightarrow x=25$

Therefore, the required number is 25.
