Question

translate this phrase into an algebraic expression: 20 more than twice jennys height use the variable j to represent jennys height.

Explanation:

Step1: Identify Jenny's height

Let \( j \) represent Jenny's height.

Step2: Find twice Jenny's height

Twice Jenny's height means multiplying her height by 2, so it is \( 2j \).

Step3: Add 20 to twice Jenny's height

"20 more than" twice Jenny's height means adding 20 to \( 2j \), so the expression is \( 2j + 20 \).

Answer:

\( 2j + 20 \)
