Molly, Ryan and Bianca, our cousins Molly is years old. Ryan is four years older than Molly. Bianca’s age is why years less than twice Spain’s age write an expression that represents Ryan age in terms of M.
Let's break down the problem:
1. Molly is years old. We don't know her exact age, so let's represent it by the variable M.
2. Ryan is four years older than Molly. So we take Molly's age (M) and add four years: M + 4.
3. Bianca's age is why years less than twice Spain's age. Let's represent Spain's age by the variable S. According to the problem, Bianca's age is why years less than twice Spain's age, which can be written as 2S - y.
Therefore, the expression that represents Ryan's age in terms of M is: M + 4.
Note that the information about Bianca's age is not needed to represent Ryan's age.
