If m<3 = 7x + 40 and m<6 = 3x – 20, find x

x = 34. 13. If ∠A and ∠B are vertical angles and m∠A = 7x - 5 and m∠B ... 6. 1. – 9. Solve the following: 1. if m∠7 = 100o, find m∠3 = 100 ... m∠ABD = 3x + 20 and m∠BDC = x + 40.

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
