An athletic trainer uses 50 inches of athletic tape on an ankle how many angels can be taken with a 2000 cm roll of tape

15

Explanation:

Firstly, it should be noted that:

1 inch = 2.54 centimetres

Therefore, 50 inches will be:

= 50 × 2.54

= 127 centimeters

Therefore, the number of ankles that can be taken with a 2000 cm roll of tape will be:

= 2000/127

= 15.74

Therefore, 15 ankles can be taken.

7 - (-11) would become 7 + 11, because the minus symbol would turn the negative into a positive. The answer is 7 + 11 = 18.
