Question

Help!! Fan and Medal :)
I have to solve the inequality

2/3(x - 12) 11 years ago

Answer 1

This is what I have so far
2/3x - 8 <or equal to x + 8

Answer 2

@cj49 @mathmath333

Answer 3

8... 4+4+4=12 so 2/3 of 12 = 4+4 =8

Answer 4

im pretty sure thats not how you solve it...thats not how I've solved any of the other problems...

Answer 5

\[2/3(x - 12) \le x + 8\]

Answer 6

thats the problem....

Answer 7

Answer 8

Well, Inequalities are hard. Let's see if I can remember how to do them.

Answer 9

2/3(x−12)≤x+8
2/3x - 8 ≤ x + 8

Thats as far as I've gotten...I just distributed 2/3

Answer 10

idk y it came out like that its supposed to be less than or equal to sign

Answer 11

\[0 \le 3x^2+16x-66 \]
is coming

Answer 12
