How much water should be added to 10 mL of 14% alcohol solution to reduce the concentration to 5%? We should add___mL.

X = 2 mL

Step-by-step explanation:

Let's do it  

X = the amount of water added to the solution (in mL)

.06(10) = .05(10 + X)

.6 = .5 + .05X

.1 = .05X

2 = X

X = 2 mL

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.
