Answer:
30 adult tickets and 24 kid tickets
Step-by-step explanation:
set up equations
x=adult tickets
y=kid tickets
x(adult tickets)+y(kid tickets)=54(people in total)
x+y=54
$8x+$5y=$360
$8 per ticket for adults
$5 per ticket for kids
total of $360 earned
8x+5y=360
↓
x+y=54
8x+5y=360
solve by elimination or substitution or even graph to get
(x,y)=(30,24)
x=30
y=24
Answer:
90
45 x 200
100
= 90
Step-by-step explanation:

1) Substitution from definition.
2) We use 
3) We are changing the order of 3 and
.
4) We add 1 and 3
and we get 
5) Substitution from definition (but the other way than at the beginning).
E is located at (-2,-4)
F is located at (2,2)
To find the midpoint, add the 2 X values together and divide by two, then do the same with the y values:
X = -2 + 2 = 0/2 = 0
Y = -4 + 2 = -2/2 = -1
The midpoint is located at (0,-1)
Answer:
16.8
Step-by-step explanation:
Because 2 to 8.4 is a scale factor of 1:4.2, you must solve 4*4.2. 4*4.2=16.8, so side OM is 16.8.
