Let be "e" the number of easy puzzles Tina solved and "h" the number of hard puzzles Tina solved.
Set up a system of equations:

You can use the Eliminationn Method to solve this system of equations:
- Multiply the first equation by -30.
- Add the equations.
- Solve for "h".
Therefore, through this proccedure, you get:

Answer:
7x+72xy
Step-by-step explanation:
7x+8x(9y)=7x+72xy
The area of the sidewalk is 72 square units. Solution: First, multiply 10 by 12 which equals 120. Then, subtract 6x8=48. So, therefore, 120-48= 72
Answer:
4
Step-by-step explanation:
If ten people each get three slices, they will need 30 pieces.
10 x 3 = 30
Each pizza has 8 slices, so we divide 30 by 8 to get the number of pizzas needed.
30 / 8 = 3.75
You can't buy 3.75 pizzas, so you must get 4 to ensure everyone gets enough.
