Answer:
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).
Answer:
k = 9
Step-by-step explanation:

k = 9
X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
