Solve the system of equations by substitution what is the solution for x when 2x + y = 1 and 4x + 2y = -1

No solutions

Step-by-step explanation:

2x+y=1

Y=1-2x

4x+2-4x=1

2=/1

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
