x-5>=7
x>=12

x+5 = 7 - (2x) 3x = 2 x = 2/3 The number is 2/3

25-n/5=18 -n/5 = 18-25 -n/5=-7 -n=-7*5 -n=-35 n=35
the product of -6 and a number, x, decreased by 9, is -33. what is the number?

(5 - x) - 7
to triple a number that was decreased by five you subtract 5 and then multiply by three. for example if you where given 10 you would 12-5=7 -> 7*3=21
x+5 = 7 - (2x) 3x = 2 x = 2/3 The number is 2/3
10x + 5 > 12x - 2 7 > 2x 7/2 > x

Factor them both. 1 x 5 = 5 1 x 7 = 7 Discard the common factor (1) and combine the remaining ones 5 x 7 = 35 35 is the lowest (least) number that both 5 and 7 will go into evenly.
Since the range is 3 and the least number is 4, the greatest number is 7.Since Kevin kept trucking of the number of pages he read only for the last 5 days, and the mode is 5 (5 appears at least twice) we list the data such as 4 5 5 6 7 or 4 5 5 5 7.
It is: 12 ≤ N - 7
