Mathematics

horsena [70]3 years ago
6 0

Start with

-2x-4 < 3x+21

Add 2x to both sides:

-4 < 5x+21

Subtract 21 from both sides:

-25 < 5x

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

-5 < x

So, the answer is x > -5

The average score of those students who passed a test was 65, the average score of those who did not pass was 35, and the overal
FrozenT [24]

Answer:

60%

Step-by-step explanation:

To find the total pass = 65 * number of student that passed, let it be be represented by P and number of students that failed F

Total pass = 65p

And total fail = 35F

For the total pass and failure will be 53(P+F)

Equating to total pass and total fail

65P +35F = 53( P+ F)

65P+35F = 53P+ 53F

65P-53P =53F-35F

12P=18F

2P= 3F

Hence there are 3 passing scores for every 2 failure scores, hence there are a multiple of 5 scores and the same multiple of 3 passing scores.

3/5 * 100= 60%
