1. the sum of 2 numbers is 61. the greater number is 9 more than the smaller number. write and solve an equation to find the 2 numbers.

Let the smaller number be x , and the greater is 9 more then the smaller number, therefore greater number is x+9 . And there sum is 61, that is

x+x+9=61

2x+9 = 61

And that's the required equation .

Subtracting 9 from both sides

2x= 52

Dividing by 2 to both sides

x =26 .

So the smaller number is 26 and greater number is 26+9=35 .

Therefore the numbers are 26 and 35 .

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
