Answer:
40 adult tickets 68 student tickets
Step-by-step explanation:
8a + 4s = 592
4(a + s = 108)
8a + 4s = 592
4a+ 4s = 432 -
------------------------------
4a = 160
a= 40
s = 180-40
s =68

Answer:
first or last depending how you are rounding the decimal
=> the best fit is the first one
Step-by-step explanation:
y = 2.55x - 2.15 when x = 5 => y = 10.6 approximately 11
y = 3.21x - 1.75 when x = 5 => y = 14.3 cannot equal or approximately 11
y = -2.15x + 2.55 when x = 5 => y = -8.2 cannot equal or approximately 11
y = 1.75x + 3.15 when x = 5 => y = 11.9 approximately 11

Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
