x = child tickets
y = adult tickets
x + y = 141
5.60x + 9.30y = 974.60
y = 141 - x
5.60x + 9.30 ( 141 - x ) = 974.60
5.60x + 1311.3 - 9.30x = 974.60
 -3.70x + 1311.3 = 974.60
 -3.70x = 974.60 - 1311.3
 -3.70x = -336.7
 x = 91
91 child tickets were sold that day

Answer:
D
Step-by-step explanation:
The absolute value of a number is the actual distance of the number from zero. So, it is always a positive number. No negative value.
A) I -4.5I = 4.5    TRUE
B) I 0I  < I -45I   TRUE   
Reason: 0 < 45
C) I 45 I > 0         TRUE
D) I4.5 I > I - 45 I     FALSE
Reason: 4.5is not greater than 45
 
        
             
        
        
        
Answer:
let the number of cows = x 
let the number of chickens = y
since there are 42 heads: 
x + y = 42
and since a cow has 4 legs, and a chicken has 2 
4x + 2y = 144
from first equation: 
x + y  = 42 
x = 42 - y (now, we will substitute this in the second equation)
4(42 - y) + 2y = 144 
168 - 4y + 2y  = 144
2y = 168 - 144 
2y = 24 
y = 12
now, we know the number of chickens. we will replace y with 12 in the first equation since it is more simpler 
x + 12 = 42
x = 30
So, there are 30 cows and 12 chickens

I think the answer is 2 because the unit price = price/total amount or weight
Price = 0.75 or 75 cents
Total Amount or weight = 5.25 pounds
Hope this helped☺☺
