What is the value of x in the solution to the system of equations below? 2x + y = 5
-3x - 5y = 3

(4,-3)

Step-by-step explanation:

-3*5-y/2 - 5y=3

-15-7y/2=3

x=5-y/2

y=-3

x=5-(-3)/2

x=4 , y=-3

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
