Answer:
8 books
Step-by-step explanation:
Earning for each ticket is $0.25 and for each book is $2
If total earning for 4 tickets and x books is $17, then the equation is:
- 0.25*4 + 2x = 17
- 1 + 2x = 17
- 2x = 16
- x = 16/2
- x = 8
So Molly purchased 8 books
Answer:
7x^6×(9×^6-5)
Step-by-step explanation:
63x^12-35x^6
7x^6×(9×^6-5)
Answer: 
Step-by-step explanation:
Given the following equation:

You can follow these steps in order to solve for "x" and find its value:
1. Apply Distributive property on the right side of the equation:

2. Subract
from both sides and add the like terms:

3. Subtract 1.8 from both sides:

4. Finally, divide both side of the equation by -1.5:

I think that the answer is $569.8. 550 times 0.072 times 0.5 (half a year) is 19.8, then 550 + 19.8 is 569.8.
