The sum of 11 and the product of 2 and a number r is equal to [tex]11 + 2r[/tex]
- 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 = [tex]2[/tex] × [tex]r[/tex] [tex]= 2r[/tex]
Next, we would sum the above up with 11;
[tex]11 + 2r[/tex]
Therefore, the sum of 11 and the product of 2 and a number r is equal to [tex]11 + 2r[/tex]
