Question 275353
solving multi-step inequalities 
1) -0.59 < (t/-4) -0.09 
Multiply the left and the right side by 100 to
get rid of the denominators:
---
-59 < -25t - 9
Add 25t to the left side and to the right side to get:
25t -59 < -9
---
Add 59 to the left side and to the right side to get:
25t < 50
---
Divide both sides by 25 to solve for "t":
t < 2
=======================================================

2) (z+5)/2 < (4-z)/7
Multiply both sides 14 to get:
7(z+5) < 2(4-z)
---
Use the distributive law on both sides of the inequality to get:
7z + 35 < 8 - 2z
Add 2z to both sides to get:
9z + 35 < 8
Subtract 35 from both sides to get:
9z < -27
Divide both sides by 9 to get:
z < -3
======================================
Good luck with you studies.
