Question

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

Answer 1

The question is the following: "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? The 289 points that he needs will be a sum of all the points he received, 3 of which we know and the forth one will be x. So the Left side will be: 72 + 78 + 70 + x Now, he needs to have 289 points or more - so the answer is :B. 72 + 78 + 70 + x ≥ 289 (equal or greater than)

Answer 2

Answer:  The correct option is (B) $72+78+70+x\geq 289.$

Step-by-step explanation: Given that John must have at least 289 test points to pass his math class. He already has test scores of 72, 78, and 70.

We are to select the inequality that will  him at least how many more points he needs to pass the class.

Let, 'x' represents the number of points he needs to pass the class.

Since John must have at least 289 points to pass the class, so the sum of 72, 78, 70 and x must be greater than or equal to 289.

Therefore, the  inequality that will  him at least how many more points he needs to pass the class is

$72+78+70+x\geq 289.$

Thus, the required inequality is $72+78+70+x\geq 289.$

Option (B) is correct.
