A lookout tower above a canyon is 4 meters above ground level. The depth of the canyon is 16 meters below ground level. If 0 represents ground level, which number sentence correctly compares their distances above and below ground level? A) 4<-16

B)4>-16

C)-4<16

D)-4>16

B

Step-by-step explanation:

4 meters above. So 4 will not be negative, this eliminates C and D.

16 is definitely negative. So that eliminates C and D again.

< the number on the left of this is smaller than the right

> the number of the right of this is bigger than the left

4 is larger than -16

4>-16

B

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
