Answer:
Total weight of gravel on the roof =
Step-by-step Explanation:
The area Adams planned to cover with gravel can be divided into 3 rectangles as shown in the diagram attached.
We would have 3 rectangles. See the attachment below to check out how we arrive at the dimensions of the 3 rectangles.
Area of rectangle = L*W
Area to be covered by gravel = area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area to be covered with gravel =
Total weight of gravel on the roof = 12 pounds per square foot multiplied by total area of the roof to be covered =

Let's call <em />the number of pages we <em>have </em>read 
. To find the number of pages we have <em>left</em> to read, we'll need to subtract the number of pages we've read from the total number of pages in the book. Our total page count is 193, and the number of pages we've read is the unknown , so the number of pages we <em />haven't read can be written as 
. With that knowledge, let's construct the rest of our equation.
"He has read three pages more than one-fourth of the number of pages he hasn't yet read." The first key phrase here is "he has read." What this means is that the number of pages he's read, which we've named, is equal to everything in the rest of the sentence. "Thee pages more than" means that we're going to be adding 3 to whatever the next quantity described is, which, in this case, is "one-fourth of the number of pages he hasn't yet read." We already established earlier that "the number of pages he hasn't yet read" is , so one-fourth of that would be 
. Putting everything together, we get the following equation:
To solve for, we might first want to eliminate the fraction 1/4 by multiplying both sides of the equation by 4, obtaining
Solving for m, we get:
Now that we have m, it's a simple matter to solve for:
So, he has not yet read 152 pages.
