Question

what is the value of the unknown number in the verbal description 5 times the sum of 12 and a number is 80

Answer 1

The number is 4

5 times the sum of 12 and 4 is 80

Answer 2

Unknown number is 4.

Explanation:

Let the number is x.

The verbal statement says " 5 times the sum of 12 and a number is 80".

So the algebraic representation of the statement will be

5(x + 12) = 80

Now we can solve this equation to get the unknown number x.

5x + 60 = 80

We will subtract 60 from each side of the equation.

(5x + 60) - 60 = 80 - 60

5x = 20

Now divide both the sides of the equation by 5

`(5x)/(5)=(20)/(5)`

x = 4

Therefore, unknown number is 4.
