Melanie is reading a book that is 300 pages long. if she has read 210 pages of the book, what percent of the book has she read?

She has read 70 %  of the book.

Step-by-step explanation:

Given  : Melanie is reading a book that is 300 pages long. If she has read 210 pages of the book,

To find :  what percent of the book has she read.

Solution : We have given

Total pages in book = 300 pages .

She read  = 210 .

Percentage she read (%) = .

Percentage she read (%) = .

Percentage she read (%) = .

Percentage she read (%) =  70 % .

Therefore, She has read 70 %  of the book.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
