11 : 12.....11 + 12 = 23
boys : 11/23 * 460 = 5060/23 = 220 <===
girls : 12/23 * 460 = 5520/23 = 240
        
             
        
        
        
Answer:
180/t = r
Step-by-step explanation:
In this question, we would have to write an equation that represents the scenario given.
We know that the car traveled 180 miles at a constant rate.
We would use the y = mx + b format for the equation, but replacing the variables with "r" and "t"
We know that 180 will be our y-variable, since that would be the base of the equation:
180 = ???
And to find how long/fast it will take the car, we would need to multiply the rate of speed "r" and time "t" in order to get our distance.
Plug it into the equation:
180 = rt
With this set up, you can find the rate of speed of the car when you know the time.
You would simply solve it as:
180/t = r
 
        
             
        
        
        
Hey there!! 
Let us take the price of the redwood as ' x ' and pine as ' y ' 
Then , we take it into an equation. We get, 
50x + 80y = 285 -------------- ( 1 ) 
80x + 50y = 339 -------------- ( 2 ) 
Now, multiply the first equation with 8 and the second equation with 5 
400x + 640y = 2280 
400x + 250y = 1695 
Now subtract the second equation from the first 
390y = 585 
y = 585 / 390 
y = $1.5 
Now substitute this into any equation 
50x + ( 80 ) ( 1.5 ) = 285 
50x + 120 = 285 
50x = 165 
x = 165 / 50 
x = $3.3 
Redwood = $3.3 
Pine = $1.5 
Hope helps!
 
        
             
        
        
        
Answer:
E. 3x + 6 = 2x + 9
Step-by-step explanation:
The total number of charms that Lydia has in term of x
6 + 3x
The total number of charms that Claudia has in term of x
9 + 2x
Since they have the same number of charms, we can set these 2 equations above equals to each other
6 + 3x = 9 + 2x
x = 9-6 = 3
So E is the correct answer
