Answer:
Step-by-step explanation:
a + c = 257
12a + 8c = 2576
-12a - 12c = -3084
12a + 8c = 2576
-4c = -508
c = 127 children tickets
a + 127 = 257
a = 130 adult tickets
It’s extremely blurry and hard to see. But if I’m correct it looks like this:
3(x+1)
7(x+4)
We can solve these problems by simplifying.
The first answer is: 3x+3
The second answer is: 7x+28
I’m not completely sure that you wanted those simplified, but that’s how I did it. If you need it calculated differently, please let me know!

Answer:
Between 10 and 11.
Step-by-step explanation:
To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)
10²= 100
11²= 121
Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.
x+y = 90
x=2y+9
2y+9+y=90
3y=81
y= 27 Emily's age
x= 2*27+9 = 63 Matt's age
