Question

Solve each inequality. Graph and check the solution.

1. -3x > -18 ____________________

2. - y/2 < 4 __________________

3. -1 1b > 55 __________________

4. -c/2 < -1.5 _____________________

5. -x/5 > 1/20 ___________________________

6. 0.9 < -r ______________________________

7. -2b > 3 __________________________

8. -a/0.5 > -70 ________________________

Answer 1

Just divide and multiply BUT when you divide or multiply by negative numbers you switch the symbol.

#1 is -18÷-3= 6; x is less than 6
#2 is 4×-2= -8; y is less than -8
#3 I don't understand the question
#4 -1.5×-2= 3; c is less than 3
#5 is 1/20×-5= -0.25; x is less than -0.25
#6 is not possible
#7 is 3÷-2=-1.5; b is greater than -1.5
#8 is -70÷-0.5= 35; a is greater than 35

Tbh I don't think any of these are right but I tried and it took me awhile so :/
