Statement by Elaine

 When you add two rational numbers, the sign depends on how many negative numbers you have.

Incorrect Statement

When you add two rational numbers , sign of the result depend on sign of Bigger Rational number , that is whether sign behind larger rational number is either positive or Negative.

Now, if both the rational number which needs to be added

1.→ Are of positive sign , the expression yields Positive result.

   6 +5=11

2.→If one is positive and another one is negative , one rational number must be subtracted from another and sign behind result is of larger rational number.

 →10 +(-11)= -1, as 11 is greater and it has negative sign behind it, so result will be negative Integer.

→ -5+8=3,larger rational number is Positive.

3.→ If both are of negative sign , result will be negative rational number.

  -5-6= -11

i do not know the answer

step-by-step explanation:

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
