Answer:

C: 11/42

Step-by-step explanation:

-1/6 + (-3/7)

This can also be written as -1/6 + 3/7

Find the LCD: 42

Divide 42 by the original denominators: 42 / 6 = 7. 42 / 7 = 6

Multiply the numerators by the quotient: -1 x 7 = -7. 3 x 6 = 18

New equation: -7/42 + 18/42

Focus on the numerators: -7 + 18 = 11

Put it all together: 11/42

From a survey of 60 students attending a university, it was found that 9 were living off campus, 36 were undergraduates, and 3 w
lana66690 [7]
I think the question has to do with the number of students who are attending the university but is neither an undergraduate nor living off-campus. To help us solve this problem, we use the Venn diagram as shown in the picture. The intersection of the 2 circles would be 3 students. The students in the 'students living off-campus' circle would be 9 - 2 = 6, while the undergraduate students would be 36-3 = 33. The total number of students inside all the circles and outside the circles should sum up to 60 students.

6 + 3 + 33 + x = 60
x = 60 - 6 - 3 - 3
x = 18 students

Therefore, there are 18 students who are neither an undergraduate nor living off-campus
