Translate this phrase into an algebraic expression. \[ 20 \text { increased by twice Janelle's age } \] Use the variable \( j \) to represent Janelle's age.

To translate the phrase "20 increased by twice Janelle's age" into an algebraic expression, you'll want to first identify the components. "Twice Janelle's age" translates to \( 2j \) (where \( j \) is her age). So, if you increase 20 by this amount, the full expression is: \[ 20 + 2j \] This represents the total after adding twice her age to 20. Now you have a neat little formula for whatever calculations about Janelle's age you want to tackle! And remember, in algebra, the beauty lies in how these expressions can help you solve real-life problems! For example, if you knew Janelle's age, you could easily calculate the total by plugging in her age into the expression. Isn't math just stunningly helpful like that?
