Answer: 45
Step-by-step explanation: 21 x 3 = 63, because 3x3 is 9. 9 tickets with a $2 discount would mean you take off $18, so I believe the answer would be 63-18=45.
Answer:
Step-by-step explanation:
2y = -x +9
3x - 6y = -15
The solution is the value of x and y that will make the two equations true in the same time.
3x-6y = -15; divide both sides by 3
x-2y = -5; substitute 2y for -x+9 because the first equation tell us they are equal
x-(-x+9) = -5; open parenthesis
x+x-9 = -5 ; add 9 to both sides and combine like terms
2x = -5 +9; 2x = 4; divide both sides by 2
x= 2
Substitute x for 2
2y = -x+9 ; 2y = -2 +9 ; 2y = 7; y = 7/2 = 3.5
Solution is (2, 3.5)

Answer: Anita's
Step-by-step explanation:
Anita's shape would have the longest sides because she only has 4 total sides, while the others have 5, 6, and 10
This means that if the total perimeter for each of the shapes was 10 units,
Anita's shape would have side lengths of about 2.5 units while the others would have side lengths of 2, 1.6, and 1 units.
This means Anita's shape has the longest sides
