John must have at least 289 test points to pass his math class. he already has test scores of 72, 78, and 70. which inequality will tell him at least how many more points he needs to pass the class? a. 72 + 78 + 70 + x < 289 b. 72 + 78 + 70 + x ≥ 289 c. 72 + 78 + 70 + x ≤ 289 d. 72 + 78 + 70 + x > 289

Hi there!

As we see, John needs to have a total of at least 289 test points to pass the math class and he already has 3 test scores. The x represents the 4th test score, which is unknown as of now. The key words at least mean that the sign of the inequality will be greater than or equal to (≥). The inequality would be 72 + 78 + 70 + x ≥ 289. B is the only answer choice that has that inequality. Therefore, the answer is B.

pretty sure 750 each month!

126 maybe. sorry
