Question

Translate into an algebraic expression and simplify if possible. The value of a number whose units digit is x and whose tens digit is three more than the units digit.

Answer 1

Answer: 11x + 30

Step-by-step explanation: Algebraic expression is a way of use letters to express relationships between algarisms.

For this question:

Units digit = x

Tens digit = 10(x + 3)

The number in question is:

10(x + 3) + x

10x + 30 + x

To simplify, add, subtract, multipy or divide similar terms:

As x is of the first order:

10x + x + 30

11x + 30

The simplified algebraic expression is 11x + 30
