Answer:

n < 2p + 7k - 4

Step-by-step explanation:

Isolate the variable, n. Do the opposite of PEMDAS. Treat the > like an equal sign, what you do to one side, you do to the other.

First, subtract 21k and 9p from both sides:

21k (-21k) - 3n + 9p (-9p) > 3p (-9p) + 12 (-21k)

-3n > (3p - 9p) - 21k + 12

Simplify. Combine like terms:

-3n > (3p - 9p) - 21k + 12

-3n > (-6p) - 21k + 12

-3n > -6p - 21k + 12

Isolate the variable, n. Note that when you divide by -3, you divide from all terms, and you flip the sign:

(-3n)/-3 > (-6p - 21k + 12)/-3

n < (-6p - 21k + 12)/-3

n < (-6p)/-3 + (-21k)/-3 + (12/-3)

n < 2p + 7k - 4

n < 2p + 7k - 4 is your answer.

MrMuchimi

Answer:

The time a student learns mathematics is important for their score

Step-by-step explanation:

Observe the boxes diagrams. Where the horizontal axis represents the score obtained by the students in the test.

The vertical lines that divide the boxes in two represent the value of the median.

The median is the value that divides 50% of the data.

For the class of the morning the value of the median is 50 points, with a maximum value of 80 and a minimum value of 10.

For the afternoon class, the median value is 65 points with a minimum value of 30 and a maximum value of 100.

This indicates that in general, the highest number of high scores were obtained in the afternoon class.

Therefore it can be said that the time a student learns mathematics is important for their  score

Subtracting 28 from both sides tells you the range of values you need to be looking at.

  28 + x > 42

  x > 14

Any values more than 14 will make the inequality true. Three of them are ...
