Answer:

Step-by-step explanation:

Number of cubes = Volume of rectangular prism / Volume of 1 cube

Volume of rectangular prism= length * width * height

              =\frac{3}{4}*1*\frac{1}{4}\\\\=\frac{3}{16}cubic inches

Volume of Cube= edge * edge *edge

                  =\frac{1}{4}*\frac{1}{4}*\frac{1}{4}\\\\=\frac{1}{64}cubic inches

Number of cubes= (3/16)÷(1/64)

            =\frac{3}{16}*\frac{64}{1}\\\\=3*4

            = 12 cubes

Solve.<br><br> 5x-2y&lt;10<br> I give Brainliest!
Anestetic [448]
<h2>Answer:</h2>

This is impossible to solve.

<h2>Step-by-step explanation:</h2>

For an equation or inequality to be solvable, there must be the same number of inequalities as variables. Here, there is an x and there is a y. This means that you need at least two inequalities to solve it.

You can, however, rearrange to get x or y on one side.

This can be done for x:

5x < 10 + 2y

x < 2 + 2/5y

Or it can be done for y:

5x < 10 + 2y

5x - 10 < 2y

2.5x - 5 < y

4 = 1 - n + 4? Geometry btw
eimsori [14]

Answer:

N = -7

Step-by-step explanation:

4 = 1 - n -4

Subtract the numbers first

1 - 4 = -3

Then rearrange the terms

4 = -3 - n

-----> 4 = n - -3

The you add 3 to both sides of the equations

4 + 3 = -n - 3 + 3
