It means convert the value of 12 from a number system based on 10 (our usual counting system) to a number system based on 5. In base 5 you would count to 12 this way: 1 2 3 4 10 11 12 13 14 20 21 22 Perhaps you have been learning a conversion formula. That should give you the same answer.
Given: 2X + 2Y = 42X + Y = 42/2X + Y = 211 + 20 =212 + 19 =213 + 18 =214 + 17 =215 + 16 =216 + 15 =217 + 14 =218 + 13 =219 + 12 =2110 + 11 =21Given: XY = 1048 x 13 = 104X=8, 13Y=13, 8
Division
x can be -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -57829728 and so on... anything less than -1.
x + 4y = -14 eqn12x + 3y = 13 eqn2Using the elimination method we multiply eqn1 by 22x + 8y = -28 eqn1bSubtract eqn2 from eqn1b2x + 8y = -28 eqn1b2x + 3y = 13 eqn25y =-41y = -8 and 1/5substituting this into eqn1 we getx +4 (-41/5) = -14x = (14*5) / (41 *4)x = (35/82)
The average mean is: (11+12+13+14+15)/5 = 13

Mean = (15 + 12 + 16 + 13)/4 = 56/4 = 14
6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16
12, 13, &14
13 ((12 + 14)/2) = 13
Mean = 14 Median = 12 Mode = 12
There are 14 even numbers between 12 and 40. To calculate this, you can use the formula for finding the number of integers in a range: (largest number - smallest number) / 2 + 1. In this case, (40 - 12) / 2 + 1 = 28 / 2 + 1 = 14. So, there are 14 even numbers between 12 and 40.
15*14*13*12 = 32,76015*14*13*12 = 32,76015*14*13*12 = 32,76015*14*13*12 = 32,760
7, 10, 11, 12, 13, 14, 17
The mean of those numbers is equal to 12.916 recurring (that is, 12.91666....)
