Answer 1

Answer:

B. 72 + 78 + 70 + x > 289

Step-by-step explanation:

To solve this problem, you just have to remember that "at leat" means a least value, that is, John must have 289 or more points to pass the exam. Therefore is he has > 289, he definitely will pass.

So, the right expression must include the sum of all scores with a > sign.

The exact expression would be

$72+78+70>289$

Therefore, the right answer is B.

Answer 2

B. 72 + 78 + 70 + x > 289
