A)
The time a cake must bake is between 25 minutes and 30 minutes, inclusive.
(1 point)
25 < x < 30
25 < x < 30
25 < x> 30
25 < x > 30
25 ≤ x ≤ 30
The correct answer is: 25 < x < 30.
To understand how to determine the correct inequality, let's break it down:
25 < x < 30 means that the variable "x" (representing the baking time for the cake) is greater than 25 and less than 30. In other words, the baking time can be any value between 25 and 30, including 25 and 30 themselves.
On the other hand, if we had 25 < x > 30, this would be incorrect. It suggests that the baking time is greater than 25 and also greater than 30, which doesn't make sense in the context of the problem.
Similarly, if we had 25 < x < 30 or 25 < x > 30, these would also be incorrect because they mix the direction of the inequality symbols.
Therefore, the correct inequality is 25 < x < 30.
The correct answer is:
25 ≤ x ≤ 30
