Which is the missing value in the proportion 4/5=x/30

x=24

Step-by-step explanation:

By cross multiplying and we get

5x=30*4

5x=120

x=120/5

x=24 (which makes sense because in order to get a denominator of 30 from 5 you need to multiply it by 6, and then the numerator would also be multiplied by 6 (4*6=24) )

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
