<span>To find out how much Newton would pay you take the cruise cost of $1920.96 and divide by $720 to find out it would take 3 months for Newton to pay off the balance at $720 per month. The cost of the cruise would be $1920.96 + ($1920.96-$720)*0.186+ ($1920-$1440)*0.186)</span>

Since there isn't a line under the < sign, this means that we used a dotted or dashed line. The dotted or dashed line indicates that we do NOT include the boundary as part of the solution set. 
Since y is isolated and we have a less than sign, this means we shade below the dashed/dotted boundary line. Specifically, the boundary line is the graph of y = 2x+1. This boundary line goes through (0,1) and (1,3). Again, points on this boundary line are NOT part of the solution set. 
So in summary we have:
A dashed or dotted boundary line
The shaded region is below the dashed/dotted boundary line.
        
             
        
        
        
1) 55% is girls, then 
100-55=45% is boys.
2) 45%=0.45                                     or  2) 400 ----100%
3)400*0.45= 180 boys                                 x -----45%      x=400*45/100=180 boys
Answer is 180 boys.
        
             
        
        
        
5/14 is the answer. I'll do my best bud

Steps↓
Convert 2 1/2 to an improper fraction:
2 + 2+ 1 over 2
Once you add the numbers, that will be 5/2.
 Now, multiply that with 1/7:
5/2 • 1/7
Your answer will be 5/14
Therefore, Rock A weighs 5/14 pounds
