Explanation:

if you divide 135 and 18 you get 7.5 which in other words can be h=7.5

Answer 2

Equation: 18h = 135

h = 7.5

Explanation:

Let's denote the time Mary takes to finish reading the book in hours as h. We know that she can read 18 pages in an hour. The total number of pages in the book is 135. The equation that can be used to find the value of h is:

`\sf 18h = 135`

Now, let's solve for h:

`\sf h = (135)/(18)`

Simplify the fraction:

`\sf h = 7.5`

So, the equation to find the value of h is 18h = 135, and the time she takes to complete the book is h = 7.5 hours.
