At the city museum, child admission is $5.60 and adult admission is $9.30. On Sunday, 141 tickets were sold for a total sales of
IrinaK [193]

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

Solve the system by substitution.<br><br> 6x + 3y = -6<br> 2x + y = -2
Mariana [72]
Solutions 

First Lets solve for this equation 6x + 3y = -6&#10; 

6x + 3y = -6&#10; 

6x+3(-2-2x)=-6&#10;&#10; &#10; 

-6=-6 

Therefore this given equation is a <span>dependent system. 
</span>
<span>Solve for </span>2x + y = -2 

2x+y=-2 

y=-2-2x&#10;&#10; &#10;&#10; &#10; 

There are too many solutions to these equations.

Can someone please help??
Vsevolod [243]

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
