5. solve t+16 greater than = 6. the solution is {t|t greater than =__?
t+16 >= 6
t >= -10
6. solve. -7/2x greater than = -3/4. the solution set is {x|x__ __?
-7x/2 > = -3/4
x >= -3/4 * 2/-7
x >= 3/14
7. solve. 5x+8<53. the solution set is {x|x__ __?
5x < 53 -8
5x < 45
x < 9
8. solve. 0.7x+6 less than = 1.5x-3. the solution is {x|x__ __?
0.7x+6 < = 1.5x- 3
0.7x - 1.5x <= -3 - 6
- 0.8x <= -9
x >= 9/ 0.8
x >= 11 1/4
9. solve. 3/4(2x-2_>15. use set-builders notation to describe the complete solution set {x|x__ __?
2x -2 > 15 * 4/3
2x -2 > 20
2x > 22
x > 11
14. solve. -7 less than = 2x+3 and 2x+3<11. the solution is {x|__less than=x<__?
-7 <= 2x+3 < 11
-7 -3 <= 2x < 11+3
-10 <= 2x < 14
-5 <= x < 7

6) 2x* -3/4 <= -7
-3x<=-14
x>=14/3
7) 5x<45
x<9
8) 9<=0.8x
x>=45/9
9) 3x/2>=15+3/2
x>=11
14) -7<=2x+3 {Ans x>= -5) & 2x-13<11 {Ans x<4)
