Answer:
14 books
Step-by-step explanation:
Let b = number of books at the beginning
She sold 1/2 of the books
b - 1/2 b
This is how many she had left
Then she bought 7
b - 1/2 b + 7
this equals 14
b - 1/2 b + 7 = 14
Combine like terms
1/2 b + 7 = 14
Subtract 7 from each side
1/2 b = 14-7
1/2 b = 7
Multiply each side by 2
1/2 b * 2 = 7*2
b = 14
She started with 14 books
Answer:
you would find the slope from the midpoint to the endpoint and apply that to the other side, don't know exactly what the coordinates are.
Step-by-step explanation:
3/5 is equivalent to 6/10
the school is 6/10 miles away
the library is 1/10 miles away
6/10-1/10=5/10
From her home to her school is 5/10 or 1/2 a mile farther than from her home to the library
Y=3x^2-15x-x+5=3x^2-16x+5
(3x-1)(x-5)
-5(x^2+12+36)+22=-5x^2-24-180+22=
=-5x^2-182
