If each blue tile has 5 sides and you know you have 3 blue tiles you can multiply 5 by 3
5 x 3 = 15 sides
Next you know the total number of sides is 30 and you just figured out that your 3 blue tiles have a total of 15 sides so you can subtract 15 from 30 to find how many sides are left
30 - 15 = 15sides
Since you know that these are not blue tiles because in the question it stated that you have 3 blue tiles. These have to be sides for red tiles.
Each red tile have 3 sides so you can divide 15 by 3
15/3 = 5
There are 5 red tiles
You are the number 5
(3/16, -169/16). Creo que es correcto, tengas buenas noches
I want you to look at a clock, the 5:15 is on the right side of the clock, if you were to count each second as 3 or 4 degrees, youll have to accept that it is acute and 45* because 5 through 6 is 45* to 70*
