Answer:
S: $0.18
T: $11.73
Step-by-step explanation:
T=tickets
S=snacks
2t+3s=24
5s=28
Divide 5 with 28.
Roughly $0.18
s=0.18.
2t+3(0.18)=24
2t+0.54=24
Subtract 0.54:
2t+0.54-0.54=24-0.54
2t=23.46
Divide 2:
t=11.73
So A snack is $0.18, and a ticket is $11.73
Hope this helped!

Answer:
9 a^2 + 30 a + 25 the anwser is A
Step-by-step explanation:
Expand the following:
(3 a + 5)^2
(3 a + 5) (3 a + 5) = (3 a) (3 a) + (3 a) (5) + (5) (3 a) + (5) (5) = 9 a^2 + 15 a + 15 a + 25 = 9 a^2 + 30 a + 25:
Answer: 9 a^2 + 30 a + 25
Both the equation show a graph of a parabola. The equation y=-x^2+1 is a parabola opening downward since the x variable has a negative sign. While the equation y=x^2 is also a parabola opening upward since x^2 is positive. Both parabola have axis of symmetry on the y-axis. Vertex for the first parabola is on (0,1) while the second parabola is at the origin.
Answer:
190
Step-by-step explanation:
f(1)=8
f(2)=3f((2-1))-2, f(2)=22
f(3)=3f((3-1))-2, f(3)=64
f(4)=3f((4-1))-2, f(4)=190
