Keisha needs to memorize words on a vocabulary list for spanish class. she has memorized 18 of the words, which is one-third of the list. how many words are on the list?

18 = (1/3)x

18 = x/3

18(3) = (x/3)(3)

54 = x

There are 54 words on the list.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
