Answer:
The book is 130 pages.
Step-by-step explanation:
Lets says total number of the pages is x and remaining page after Rani reads is y. We can write below equivalents
second equivalent can be turn into:
If we subtract this equivalent from first one:
You are dividing a number (x) by three and then subtracting 1 like this. (x/3)-1
Answer:
A is the answer
Step-by-step explanation:
-X* - Y= XY
Answer:
x = - 14
Step-by-step explanation:
23 + 4 + x = 25 - 12
Combine like terms on both sides of the equation (by adding 23 and 4 on the left-hand side, and subtracting 12 from 25 on the right-hand side):
23 + 4 + x = 25 - 12
27 + x = 13
Next, subtract 27 from both sides to solve for x:
27 - 27 + x = 13 - 27
x = - 14
