Total rivets on the belts=48 rivets+30 rivets
Total rivets on the belts=78 rivets

I wish i remembered that but it has been a while
The volume of a gas in a container varies inversely with the pressure on the gas. If a gas has a volume of <span>250 </span>cubic inches under a pressure of<span>
</span><span>4 </span>pounds per square inch, what will be its volume if the pressure is increased to 20 pounds per square inch? (Round off your answer to the nearest cubic inch.)
slope = y2-y1 over x2-x1
-1 - 4= -5
-8-0 - -8
so you get -5/-8
negative divided by negative = positive
slope = 5/8
