False

Step by step explanation:

it depends on the operation you use

For example, (-4) - (-10) = 6 (positive).

So, the set of negative numbers is not "closed" to subtraction.

(-4) + (-10) = -14

(-25) + (-2) = -27

negative numbers are a closed set under addition. You can add negative numbers all day in any way you want, and you will only get negative numbers as your result.

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins

if you get paid hourly because if you get a salary you could work all week and only get paid a certain amount no matter how much you work but if you get paid hourly then you get paid for every minute you worked.
