show your work

Variable: Let x represent the grade a student earns in their Algebra 1A course.

Inequality: x ≥ 70

To define a variable, let's call it "x", which represents the grade you earn in the Algebra 1A course.

The inequality for the statement "In order to earn credit for your Algebra 1A course, you must earn at least a 70%" can be written as:

x ≥ 70

To define a variable, let's call it "score", which represents the percentage earned in the Algebra 1A course.

The inequality for the statement "In order to earn credit for your Algebra 1A course, you must earn at least a 70%." can be written as:

score ≥ 70%

This inequality states that the "score" variable must be greater than or equal to 70%, indicating that you need to earn at least 70% to qualify for credit in the Algebra 1A course.
