Answer:
![p+n=0](https://tex.z-dn.net/?f=p%2Bn%3D0)
Step-by-step explanation:
Given that Lincoln has
pennies and
nickles and that his total worth is $0,
we can express his total using the inequality:
![p+n=0](https://tex.z-dn.net/?f=p%2Bn%3D0)
Where the sum of n and p is his total
Hence, Lincoln's situation is expressed as p+n=0
Step-by-step explanation:
since both objects and sides are similar, you can set each side equal, then you cross multiply, and do subtraction, then find x.

Step-by-step explanation:
10-4(2x+7) mult 2x+7 by -4
10-8x-28
combine like terms
-18-8x
I don't even actually need to work this one out. The rule between the volumes of a cylinder and a cone is that is they have the same height and diameter, the the volume of the cone is one-third that of the cylinder. But in this case the cone's height is three times that of the cylinder. So I predict that their volumes are the exact same. But working it out, the volume of a cylinder is V=πr2h, and plugging in all the appropriate values the volume of the cylinder is 251.33 square inches. And the volume of a cone is V=πr2(h/3), and plugging in the values given to me here the volume of the cone is 251.33 square inches. Therefore their volume is the same.
