Answer:

x = 25

Step-by-step explanation:

75 (total amount of people that run) minus 40 (amount of people that lift weights and run) equals 35 (amount of people that run but don't lift weights)

120 (total amount of people surveyed) minus 65 (total amount of people that lift weights) equals 55 (total amount of people that do not lift weights)

55 (total amount of people that do not lift weights) minus 35 (total amount of people that run but don't lift weights) equals 25 (total amount of people that don't run or lift weights.

Answer:

Sample response: Yes, you can determine the number of people who do not run or lift weights by first finding that 55 people do not lift weights, and that 35 people run, but do not lift weights. Subtracting 35 from 55, you get that 20 people do not do either.
