It is: 12 ≤ N - 7

12-2n= -72n = 19n = 9.5
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
"decreased by" means "minus" 12 decreased by z means 12 - z It really is that simple.

Let the number be x 12-2x = -7 -2x = -7-12 -2x = -19 x = 9.5

x-5>=7 x>=12
12-2n= -72n = 19n = 9.5
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
"decreased by" means "minus" 12 decreased by z means 12 - z It really is that simple.
A number decreased by 4 is n-4
35 - some number = 15 and usually you are required to find the number.
8-x 8-x
"Decreased by" just means "minus," so that's C-11.
