Here is my question! first gets brainliest the question is in the picture,

8 dimes, 15 quarters

Explanation:

The number of dimes=x

The number of quarters=x+7

So the value of each dime and quarter is 0.10 and 0.25

0.1x+0.25(x+7)=4.55

0.1x+0.25x+1.75=4.55

0.35x+1.75=4.55

0.35x+1.75–1.75=4.55–1.75

0.35x=2.8

0.35x/0.35=2.8/0.35

x=8

So the number of dimes there are is 8.

The number of quarters:

x+7

=8+7

=15

So, the number of dimes and quarters in this order are: 8 and 15.

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
