Answer 1

The expression 'ten more than the product of two and a number' can be written as 10 + 2x. Evaluating when x = 3.5 gives the value 17.

Step-by-step explanation:

The expression 'ten more than the product of two and a number' can be written as: 10 + 2x, where x represents the number. To evaluate this expression when x = 3.5, substitute 3.5 in for x: 10 + 2(3.5). Simplifying, we get: 10 + 7 = 17. Therefore, when x = 3.5, the value of the expression is 17.
