Answer:
65 tickets for children
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x be the ticketsr of children
let y be the tickets of adults
Thus:
5.3 * x + 9.4 * y = 852.1
x + y = 119 => x = 119 - y
replacing, we are left with:
5.3 * (119 - y) + 9.4 * y = 852.1
630.7 - 5.3 * y + 9.4 * y = 852.1
9.4 * y - 5.3 * y = 852.1 - 630.7
4.1 * y = 221.4
y = 221.4 / 4.1
y = 54
Now to calculate x:
x = 119 - 54
x = 65
Which means that there are 65 tickets for children and 54 tickets for adults.
Answer: AC
Matrix A is a 3x3

Answer:
Perimeter of the smaller square = 9 ft
Perimeter of the larger square = 18 ft
Step-by-step explanation:
Let
Perimeter of the smaller square = x
The perimeter of the larger square is twice the perimeter of the smaller square.
Perimeter of the larger square = 2x
Total Length of the piece of wire = 27 ft
Total = smaller + larger
27 = x + 2x
27 = 3x
x = 27/3
x = 9 ft
Perimeter of the smaller square = x
= 9 ft
Perimeter of the larger square = 2x
= 2(9)
= 18 ft
Your answer is right because just looking at others doesn't match the information given. So yes, you are correct!
Hope that helped!
