Question

In order to avoid heavy traffic, Antonio can drive home after working less than 7 hours (h < 7) or after working more than 9 hours (h >9). How can these inequalities be written as one statement?

a. 7 < h < 9
b. 7 > h > 9
c. h < 7 or h > 9
d. h > 7 or h < 9

Answer 1

A is not correct because h has to be less than 7 hours. it also has to be greater than 9 hours so this condition isnt fulfilled.

B is not correct. h cannot be both larger than 9 and less than 7. I would say that answer isnt correct

C conditions are correct and written exactly as they should be. sepparated. unlike ones in B

D is oposite from C so it is not correct.
