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.
Answer:
45
Step-by-step explanation:
Subtract $34.99 from $40 to figure out how much money you have left for text messages.
You have $5.01 left and you divide that by $0.11 (cost for each text). Your answer is 45.5454. Since you can’t send 1/2 a text, your answer is 45.
For a number to be a solution to an equation, it has to satisfy the equation...it has to make the equation true.
for example :
2n + 6 = 10.....n is our unknown number
2n = 10 - 6
2n = 4
n = 4/2
n = 2...so the number that makes the equation true is 2
and to check if the number is a solution, we then sub that number back into the original equation to see if it makes the equation true.
2n + 6 = 10
2(2) + 6 = 10
4 + 6 = 10
10 = 10 (correct)
so our number (n) represents the number 2, and it does make the equation true
