Answer:
74 adult tickets and 106 children tickets
Step-by-step explanation:
let x be the number of adults tickets sold out
and y the number of chlidrens tickets that sold out for the 7:15 pm show
The equations that determine our problem are
x+y=180
12.50x+8.50y=1826
lets separate x from first equation x=180-y and replace at the second equation
12.50(180-y)+8.50y=1826
12.50*180-12.50y+8.50y=1826
2250-4y=1826
4y=2250-1826
y=424/4=106
so x=180-y=180-106=74

Answer:
Option C - 2(-5)+2(3) ; -4
Step-by-step explanation:
Distributive property means breaking up the factors and multiplying them separately
So here we have 2(-5+3) = 2(-5)+2(3) = (-10)+(6) = (-4)
So (-4) is the value.
Hope this helps you.
Answer:
14
Step-by-step explanation:
Given the data:
13 15 14 16 12
The point estimate of the population mean will be :
ΣX/ n
X = Given data points
N = sample size
ΣX = (13 + 15 + 14 + 16 + 12) = 70
N = 5
Hence,
ΣX/ N = 70 / 5
Point estimate of population mean = 14
Answer:
= 12.5 gallons
Step-by-step explanation:
50 gallons per 20 mins
50/20=5/2
5/2 per minute so 5 mins is
5/2 x 5 = 25/2
=12.5 gallons
