If x is an integer, then -x is positive true or false

An integer is a whole number  that can be positive, negative, or zero

The negative of a negative number is positive. -(-3) = +3

The negative of a positive number is negative. -(3) = -3

Zero can neither be positive nor negative

207/8 is the right

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
