(1) solve this system using the substitution method: y = 6x – 5; y = (2/3)x + 1 (2) solve this application problem using a system of equations: the springfield movie theater sold adult tickets for $4.10 each and children's tickets for $2.70 each. last thursday, a total of $331.30 was collected from 89 movie watchers. how many of each type of ticket were sold on thursday?

9x

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

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
