At a certain school, the mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together. The students must obtain at least 150 marks to achieve a satisfactory grade. A student obtains x marks in the Term 1 exam. Write an appropriate inequality to show the mark, y, that the student must obtain in the Term 3 exam in order to pass.

The inequality of the given question is x+2y ≥ 150

Step-by-step explanation:

Given,

The mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together.

And, he needs to obtain 150 to achieve the grade.

To find, the inequality to student mark

Let,

The student got x in Term 1 and y in Term 2.

To be passed, he needs to get x+2y

So, the requited inequality will be x+2y ≥ 150

Good morning ☕️

Step-by-step explanation:

the mark out of 100 for Term 1 exam and twice the mark out of 100 for the term 3 exam are added together means  x + 2y

The students must obtain at least 150 marks to achieve a satisfactory grade

means  x + 2y ≥ 150
