Find each of the numbers below. Simplify your answers as much as possible. The opposite of -4:
The opposite of 8:
The opposite of the opposite of – 2:

Step-by-step explanation:

To find the opposite of a certain number, divide it to -1 or simply change its sign. For negative numbers, their opposites are positive. For positive numbers, their opposites are negative.

For numbers 1 and 2, change their sign to find their opposite numbers. For numbers 3, it is still the same. “The opposite of the opposite of -2.” The opposite of -2 is 2, and the opposite of 2 is -2. The opposite contradicts the following words, so it will be the same.

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
