Answer: 
Step-by-step explanation:
The volume of a cube can be found with this formula:

Where "s" is the lenght of any edge of the cube.
The formula for calculate the volume of a rectangular prism is:

Where "l" is the lenght, "w" is the width and "h" is the height.
We need to find the volume of a cube box:

To find the volume of the shipping box, first we must convert the mixed number to an improper fraction:

Then the volume of the shipping box is:

Now, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube. This is:

The order of operations is
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
For this problem, we have M and D. We first do division. Not always multiplication is first.
So we divide 20 by 5, which gets you 4, and multiply by 2, which is 8.
8 IS YOUR FINAL ANSWER,
3125 !! If I was correct.
Answer: A
Step-by-step explanation:

We need to get this form: 
we need to begin by isolating y on the left side. To do this, we must subtract 4x.

Rewrite it so that we get this form: 

Since y needs to be completely isolated, divide by 4.

Divide;

Answer:
The true statements are:
Step-by-step explanation:
As we are given,
AD = 3.5 and BD = 3.5
CE = 3 and BE = 3
From the given triangle ΔABC, it is clear that:
The segment DE bisects the sides AB and BC, so
AD = BD
CE = BE
It is clear that the segment DE is parallel to the segment AC, thus
DE || AC
As DE is the midsegment between AB and BC, so
2DE = AC
1/2AC = DE
Thus, the true statements are:
