<h3>Answer:  20</h3>

===============================================================

Explanation:

Think of a Rubik's cube. Each face is composed of 9 small squares, in which the goal is to get each side to have the same color of 9 squares.

Since we have 9 squares on one face, this means we have each side that is sqrt(9) = 3 units long. Each little square is 1 unit by 1 unit.

The volume of the Rubik's cube is 3*3*3 = 27 cubic units. Meaning that we need 27 small cubes to build up the entire device. We can think of it like saying there are 9 cubes in the top row, 9 in the middle row, and 9 in the bottom row to give 9+9+9 = 27 total cubes.

This figure shows 7 such cubes, so we need 27-7 = 20 more cubes to form a complete Rubik's cube.

Which is the approximate solution to the system y = 0.5x + 3.5 and y = −A system of equations. y equals 0.5 x plus 3.5. y equals
Elena L [17]

Answer:

The approximate solution of the system of equations is the point (-2.7,2.1)

Step-by-step explanation:

we have

y=0.5x+3.5 -----> equation A

y=-\frac{2}{3}x+\frac{1}{3} -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (-2.714,2.143)

see the attached figure

therefore

The approximate solution of the system of equations is the point (-2.7,2.1)
