Question 219695: Hello, could you please help me with this inequality? I need to write the solution set in interval notation and graph it. Both of the <(less than signs) are actually equal to also, I just didn't know how to show that with the key board.
Thanks so much! I tried to work this out and I got [-1,4] but I'm not sure that's right.
-7<3x-4<8

Question 221037: Can someone please show me how to work these two examples?
0.9x + 6 ≤ 1.3x -3 The solution set should be {x|x __ __}
The second is -3 ≤ 3x-2 ≤ -1, the solution set {x| __ ≤ x ≤ __}
I have been trying for hours to figure these and just can not seem to do so. Thank you.

Question 222429: How do you know if a value is a solution for an inequality? How is this different from determining if a value is a solution to an equation? If you replace the equal sign of an equation and put an inequality sign in its place, is there ever a time when the same value will be a solution to both the equation and inequality?

Question 222547: 4th grade math - help this mother!
inequalities
the grocery store is selling frozen turkeys that weigh between 10 lbs and 20 lbs. Write two inequalities that together show the weights of the turkeys.
My daughter and I know the turkeys are between 10 and 20 lbs, and I've drawn a number line out to help explain this to her, but I do not know how to write the inequalities. Help. Thanks
