The time a cake must bake is between 25 minutes and 30 minutes, inclusive.
What is the correct expression
to represent this inequality?
The correct expression to represent this inequality is:
25 ≤ baking time ≤ 30
The correct expression to represent the time a cake must bake, between 25 minutes and 30 minutes inclusive, is:
25 ≤ baking time ≤ 30
To represent the range of time a cake must bake, you can use an inequality expression. In this case, you want to include both ends of the range, so you use the "greater than or equal to" symbol (≥) for the lower bound and the "less than or equal to" symbol (≤) for the upper bound.
The correct expression for the given problem would be:
25 ≤ baking time ≤ 30
