Kamilah’s weight has tripled since her first birthday. if w represents the amount kamilah weighed on her first birthday, write an expression to show how much kamilah weighs now.

3*w

Step-by-step explanation:

Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.

Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).
