Question

in taekwondo, a form is a sequence of moves (steps, blocks, kicks). seth knew two forms before he found out about taekwondo tournaments. he was excited to start participating in tournaments, and decided to learn one new form in preparation for each tournament he goes to. enter a variable for the number of tournaments seth participated in and use this variable to write an expression for the number of taekwondo forms seth knows. 1. by the time seth knew eleven forms, how many tournaments had he participated in? 2. seth just returned from his sixteenth tournament, where he showed off his latest form. how many forms has he learned? after completing the worksheet, graph your model.

Explanation:

Step1: Define variable

Let \( t \) be the number of tournaments.

Step2: Write expression

Seth knew 2 forms initially. He learns 1 form per tournament. So the expression is \( 2 + t \).

Question 1

Step1: Set up equation

We know the expression \( 2 + t=11 \).

Step2: Solve for \( t \)

Subtract 2 from both sides: \( t = 11 - 2 \).
\( t=9 \).

Question 2

Step1: Substitute value

Substitute \( t = 16 \) into the expression \( 2 + t \).

Step2: Calculate

\( 2+16=18 \).

Answer:

• Expression: \( 2 + t \)
• Question 1: \( 9 \)
• Question 2: \( 18 \)
