9 * 4 = 36
Or
27 / 9 = 3
36 / 9 = 4

Answer:
here,
3( x + 5 ) = 3• x+ 3 • 5 uses the distributive property correctly.
(ii) 3% of students failed all three courses, 12% failed economics and mathematics, 9% in math and business, and 10% in econ and business. In other words, the students in these groups failed at least the two mentioned courses. Then 12% - 3% = 9% failed only econ and math <em>but not</em> business; 9% - 3% = 6% failed math and business <em>but not</em> econ; and 10% - 3% = 7% failed econ and business <em>but not</em> math. These groups are mutually exclusive, so the total percentage of students that failed exactly two courses is (ii) 9% + 6% + 7% = 22%.
32% failed econ, which means 32% - 12% - 10% + 3% = 13% failed <em>only</em> econ. Similarly, 46% failed business, so 46% - 9% - 10% + 3% = 30% failed <em>only</em> business. But we don't know how many students failed math, so we can't determine how many failed <em>only</em> math... And consequently we can't determine the proportion of students that make up the other categories.
