Answer:
Salma, joe, and alan sent 14, 69, and 23 text messages respectively
Step-by-step explanation:
Given that Salma, joe, and alan sent a total of 106 text messages during the weekend, it means that
s + j + a = 106 where s, j, and a are the number of messages sent by Salma, joe, and alan respectively
Given salma sent 9 fewer messages than alan
s = a - 9
Joe sent 3 times as many messages as alan
j = 3a
hence
a - 9 + 3a + a = 106
5a - 9 = 106
5a = 106 + 9
5a = 115
Divide both sides by 5
a = 115/5
= 23
s = 23 - 9
= 14
j = 3* 23
= 69

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.
