2.7 less or equal to b + 5
A. b greater or equal to 7.7
B. b great or equal to -2.3
C. b less or equal to 2.3
D. B less or equal to -7.7
To solve the inequality 2.7 ≤ b + 5, you need to first subtract 5 from both sides:
2.7 - 5 ≤ b
-2.3 ≤ b
So, the answer is:
B. b greater or equal to -2.3
To solve the inequality 2.7 ≤ b + 5, we can start by subtracting 5 from both sides of the inequality:
2.7 - 5 ≤ b + 5 - 5
-2.3 ≤ b
So, the value of b must be greater than or equal to -2.3.
Therefore, the correct answer is B. b greater or equal to -2.3.
To solve the inequality 2.7 ≤ b + 5, we can subtract 5 from both sides to isolate the variable b:
2.7 - 5 ≤ b + 5 - 5
-2.3 ≤ b
So the answer is B. b greater or equal to -2.3.
