First you multiply 8 and 4 to get 32 and that shows you how many campers have agreed to help. Next you have to subtract 32 from 100 to know how many more people you need.
y=mx+b is the formula. So -8=-3x+5would be the answer..
since (x,y) just substitute these numbers you have it into the formulas... Take y from (5,-8) and place it into y=mx+b. Next take the slope which is -3. And then since its a postive number we <em>add</em> are x from (x,y). -8=-3x+5. We also add x next to the slope (-3) becuase we are trying to solve for x. And we <em>always</em> put it next to the slope. Hope this helps!
To start, I had similar questions and I know that it takes 3 cones to fill a cylinder. And as for the volumes: V of a cylinder= V=π r<span>2 h (pi x radius squared x height) Volume of a cone= V=</span><span>π r2 h/3 (pi x radius squared x height divided by 3)</span>
