The sum of 11 and the product of 2 and a number r is equal to \(11 + 2r\)
- Let the unknown number r.
In this exercise, you're required to write a mathematical (algebraic) expression for the given word problem.
Translating the word problem into a mathematical (algebraic) expression, we have;
Product of 2 and a number r = \(2\) × \(r\) \(= 2r\)
Next, we would sum the above up with 11;
\(11 + 2r\)
Therefore, the sum of 11 and the product of 2 and a number r is equal to \(11 + 2r\)
