The pH scale measures how acidic or basic a substance is. Bleach is said to have a pH of less than 14 and greater than 11. Model
the normal range of pH values of bleach, using a compound inequality. 11 > x > 14 11 < x < 14 11 ≤ x ≤ 14 11 ≥ x ≥ 14

Answer:
11 < x < 14
Step-by-step explanation:
<em>Bleach is said to have a pH of less than 14 and greater than 11.</em>
Let x = pH
First, we will consider individual inequalities.
- Given x is greater than 11, 11 < x (this means that x takes values higher than 11, but not 11).
- Given x is less than 14, x < 14 (this means that x takes values lower than 14, but not 14).
If we take both inequalities, we can set up a compound inequality: 11 < x < 14.
Answer:
The answer to your question is: 11 < pH < 14
Step-by-step explanation:
Data
Bleach have a pH less than 14 and greater than 11.
We have to use these symbols:
< greater than > less than
and pH will be in the middle
11 < pH < 14
This inequality means the Bleach has a pH between 11 and 14

Step-by-step explanation:
Answer: $2.55
Step-by-step explanation:
He bought the second shirt for half off the first shirt's price. He therefore bought it at:
= 19.99/2
= $10.00
Total paid for both shirts is therefore:
= 19.99 + 10
= $29.99
Sales tax is 8.5% so he paid:
= 29.99 * 8.5%
= 2.54915
= $2.55
