Answer:
Pythagorean Theorem
Step-by-step explanation:
it will find you d
x = 13
subtract x from both sides of the equation
6 = 2x - x - 7
6 = x - 7
add 7 to both sides
6 + 7 = x ⇒ x = 13
As a check
substitute this value into the equation and if both sides are equal then it is the solution
left side = 13 + 6 = 19
right side = (2 × 13) - 7 = 26 - 7 = 19
hence x = 13 is the solution
Ok this is a bit complicated.
Total: 114 days
114 divided by 3 equals 38
38 times 2 equals 76
76 books, I think.
To solve this, you need to do 1,266-451. that equals 815. then, divide 815 by 19. you should get 43. hope that helps.
