1. find the possible values for s in the inequality 12s – 20 ≤ 50 – 3s – 25

12s - 20 < 50 - 3s - 25

12s - 20 < 25 - 3s
+3s. +3s

S cancels

15s - 20 < 25
+ 20. +20

15s < 45
/15. /15

S < or equal to 3

Hello there.

1. Find the possible values for s in the inequality 12s – 20 ≤ 50 – 3s – 25

First, simplify both sides

Next, add 3s to both sides

Then, just add 20 to both sides and divide both sides by 15.

Final  s ≤ 3

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
