I think it's the last two
Step-by-step explanation:
a bouquet is 5r+3d+4f , so 75 bouquets make 75(5r+3d+4f) , which can also be written as 75(5r)+75(3d)+75(4f) (association property)

Each yard costs $1.50, so let's multiply that by 10

Marci will pay $15 for 10 yards of the ribbon.
 
        
        
        
Answer:
-7 = h
Step-by-step explanation:
15.3 + 1h = 1.3 - 1h
<u>         +1h          +1h</u>
15.3 + 2h = 1.3
Remember what you do to one side you MUST do to the other. 
  15.3 + 2h = 1.3
<u>-15.3           -15.3</u>
2h = -14
Now to isolate the variable you divide both sides by 2 to get, h = -7
Hope that helps and have a great day!
 
        
                    
             
        
        
        
Total number of pastries = 54 + 31 + 10 = 95
Number of croissants = 10
Probability of picking a croissant = 10/95
On simplifying, we get, <u>2/19</u>
