c. 7 < x < 11
d. 5 < x < 16
My answer is b. Can you check my work?
looks good
Ok, thanks!
To solve the inequality 5 < x - 2 < 11, we'll break it down into two separate inequalities and solve them individually.
First, let's solve for the lower bound: 5 < x - 2
Adding 2 to both sides of the inequality, we get 5 + 2 < x - 2 + 2, which simplifies to 7 < x.
So for the lower bound, x > 7.
Next, let's solve for the upper bound: x - 2 < 11
Adding 2 to both sides of the inequality, we get x - 2 + 2 < 11 + 2, which simplifies to x < 13.
So for the upper bound, x < 13.
Combining both results, we have 7 < x < 13.
Comparing the solution to the answer choices, the correct choice is b. Therefore, your answer is correct. Well done!
