To solve this, write a proportion of Pounds to Cost:
Pounds:     3         x
     Cost: 25.50   42.50
Cross multiply 3 and 42.50, this gives you 127.5
Then, divide by 25.5
This gives you 5.
You can buy 5 pounds with $42.50
        
                    
             
        
        
        
Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
        
             
        
        
        
Answer:
659.6 ft 
Step-by-step explanation:
x = 140 / tan 23  
x = 329.82(rounded to hundredth)
so total ground distance between the cables = 2x = 2(329.82) = 659.64 feet
 
        
             
        
        
        
Answer:
The greatest number is 18. 
Step-by-step explanation:
consecutive: following one after the other
48 ÷ 3 = 16 
16 would be the middle number 
14 : 16 : 18 
14 = smallest number
16 = middle number
18 = biggest number
14 + 16 + 18 = 48
