Answer:
the first part of the book has 659 pages and the second part has 723 pages
Step-by-step explanation:
First we have to raise 2 equations, one that shows us the relationship between one part of the book and the other, and another equation that shows us that together they give us the total of pages
x = second part
y = first part
x = y + 64
x + y = 1382
As the first equation tells us that x = y + 64 we will replace x in the second equation with (y + 64)
x + y = 1382
(y + 64) + y = 1382
y + y = 1382 - 64
2y = 1318
y = 1318/2
y = 659
now we replace in the first equation to y by its value
x = y + 64
x = 659 + 64
x = 723
so the first part of the book has 659 pages and the second part has 723
Answer:
a.
b. $37.50
Step-by-step explanation:
To find out how much the 5 were paying in total, we can add the bill and the tip. This gives us x + 10. Since there are 5 people and they are splitting the bill equally, the total amount would be divided by 5 to get the amount each person pays: 
. We already know the amount they each paid, as it is given as $9.50. Both expressions represent the same thing, do we can set them equal to each other:
Now, we can solve.
First, we can multiply by 5 on both sides to get:
47.5 = x + 10
And then subtract 10:
x = 37.5
This means the bill before the tip was $37.50
