Answer:
z=12
Step-by-step explanation:
subtract both sides by 4:
-z/3=-4
then multiply both sides by -3:
z=12
Add your bottoms in a cross pattern
Well you would take 53% then put it over 100 so you should get 53/100
Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.
Solution
2.7 ≤ b + 5 Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b Write with the variable on the left.
b ≥ - 2.3 <<<< answer
