need the answer pleasee

Question

Joe's final exam has true/false questions, worth 2 points each, and multiple choice questions, worth 5 points each. Let x be the number of true/false questions he gets correct, and let y be the number of multiple choice questions he gets correct.

He needs more than 90 points on the exam to get an A in the class. Using the values and variables given, write an inequality describing this.

Answer 1

Since each true/false question is 2 points, we can appoint the value of "2" in front of x. Remember X represents true or false questions.

Since each multiple choice question is 5 points, we can similarly appoint the value of "5" in front of y. Remember Y represents multiple choice questions.

Therefore, we are left with adding the two question type up to get at least 90 points:

2x + 5y ≥ 90
