Answer:
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
