Answer:
H. 8%
Step-by-step explanation:
27 + 19 + 4 = 50 (total weight)
4% of 50 = 2
5% of 50 = 2.5
8% of 50 = 4
12% of 50 = 6
Therefore the answer would be H, 8% because 8% of 50 is 4
Answer:

Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is

Area of the pentagon: 342 cm2
Step-by-step explanation:
The figure of the pentagon is missing: find it in attachment.
The area of the pentagon can be seen as the area of 5 equal triangles, each of them having a base equal to the length of the side of the pentagon,
L = 14.1 cm
and the height of each triangle can be found by using Pythagorean's theorem:

The area of each of the 5 triangles is

Therefore, the area of the pentagon is 5 times this area:
