Answer:
1= 10
2= -5
3= 1
Step-by-step explanation:
Keep change opposite is what I use for number 1
For 2 just subtract 8 - 3
5 will be the answer and since 8 was negative it will be negative 5 cause 8 is the bigger number.
for 3
6-5 is simple.
Volume = π (3.14)×22^2×12.5 = 18,997 inches³
Option B:
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Solution:
Given expression: 
To find the equivalent expression for the given expression.
Apply absolute value rule:
<em>If |x| ≤ m then -m ≤ x ≤ m.</em>

⇒ -5 ≤ a ≤ 5
⇒ -5 ≤ a and a ≤ 5
Switch the sides, we get
⇒ a ≥ -5 and a ≤ 5
The expression equivalent to |a| ≤ 5 is a ≥ -5 and a ≤ 5.
Option B is the correct answer.
