Suppose the number is y >>>>>So y/2 +2y/3 <14
multiply both sides by 6>>>>>>>>>. 6y/2 +6x2y/3 <14x6
3y + 4y < 84
7y <84
y <84/7
y < 12
The volume of railway car is 216 cubic meters
<em><u>Solution:</u></em>
Given that, Railway car is shaped like a rectangular prism with a length of 18 meters, a width of 3 meters and a height of 4 meters
To find: volume of railway car
<em><u>The volume of rectangular prism is given as:</u></em>

Where,
"l" is the length and "w" is the width and "h" is the height of prism
From given question,
length = 18 meters
width = 3 meters
height = 4 meters
Substituting the values, we get

Thus volume of railway car is 216 cubic meters
Slope is m in y=mx+b
Therefore m or slope is 4/5
