60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm
-36x+30
-24x+20
-18x+15
-12x+10
This isn't the same problem but it's an idea. of what you're doing.
Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6
mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)
