Help me please I have to do this

Hi there!

b=3·b=3b

This means:

1=3, 2=6, 3=9, 4=12, 5=15, 6=18, 7=21, 8=24, and 9=27.

Multiply by 3 everytime...

if b is 3, then the expression is is 3·b or 3b.

Final Result: 3b

As, we are given :

Minutes taken to fill Sylvia's bathtub with water = b minutes

Therefore,

Minutes taken to fill 3 bathtubs like Sylvia's bathtub = 3 × b minutes = 3b minutes

Hence, Minutes taken to fill 3 bathtubs like Sylvia's bathtub are 3b minutes.
