Answer:
A
Step-by-step explanation:
2(3) + (3) = 9
3(3) - 2(3) = 3
Let the total ribbon Zoe had was x feet.
Out of x feet, she used 3/8 part of it.
Hence, 
3/8 part of the original ribbon is equal to 9 feet.
Hence, we get

=> Multiply 8 on both sides.

Divide both sides by 3


Zoe had 24 feet of ribbon in starting... Answer

Answer:
The volume of the given pyramid is 300 cm³
Step-by-step explanation:
The volume of a pyramid,
, is given as follows;

The height of the pyramid = 12 cm
The side length of the square base of the pyramid = 5 cm
The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²
Therefore, by substitution, we have;

The volume of the given pyramid, V = 300 cm³.
I think an equation for this could be 5x+6=y
This can be explained as x representing how much the five friends got and y equaling the total. Hope this helps!
