Which expression represents the algebraic phrase " twelve times the sum of a number and seven-tenths

12 (x + 7/10)

Explanation:

Algebra is a branch or aspect of mathematics that deals with the combination of numbers and alphabetic letters. In other words, a mathematical expression that contains letters is termed "algebraic".

According to this question, the following algebraic phase is given: "twelve times the sum of a number and seven-tenths". The algebraic expression is as follows:

- The sum of a number, which is represented by letter "x" and seven-tenths, which mathematically means 7/10 is x + 7/10.

- twelve (12) multiplied by this will give

12 × x + 7/10

= 12 (x + 7/10)

= 12x + 84/10
