Answer:

Part a) 75W+15M > 300\ minutes

Part b) 3W+M \leq 20\ paper\ sheets

Step-by-step explanation:

Let

W------> the number of writing assignments that Makhaya completes

M-----> the number of math assignments that Makhaya completes

so

case A) Based on the number of minutes

75W+15M > 300 -----> inequality that represent the situation based on the number of minutes  

The solution is the shaded area between the positive values of W and M

see the attached figure N 1

case B) Based on the number of paper sheets

3W+M \leq 20-----> inequality that represent the situation based on the number of paper sheets

The solution is the triangular shaded area between the positive values of W and M

see the attached figure N 2
