Question

Translate the following sentence into an equation. The product of five and the sum of a number x and three is twelve.

A) 5 + 3x = 12
C) 5x + 3 =12
B) 5(x + 3) =12
D) 5x + 3 = x

Answer 1

Option B

The product of five and the sum of a number x and three is twelve is 5(x + 3) = 12

Solution:

Given that we have to translate the following sentence into equation

Given sentence is:

The product of five and the sum of a number x and three is twelve

Let the number be "x"

By given sentence,

product of five and the sum of a number x and three = 12

"Product" means multiplication and "sum" means addition

So multiplication of five and sum of x and 3 is 12

`5 * (x + 3) = 12\\\\5(x + 3) = 12`

Thus Option B is correct
