Question

I just need this problem please :)​

Answer 1

`18vw^6`

Explanation:

We can set the following equation:

`(1)/(3)5vw^3B=30v^2w^9`

Getting rid of the fraction, we can multiply both sides by 3.

`5vw^3B=90v^2w^9`

Dividing by 5, we have

`vw^3B=18v^2w^9`

Dividing by vw^3, we have

`B=18vw^6`
