Just solve x or y pls

x = 63°, y = 27°

Step-by-step explanation:

Step 1: Equation 1

( 5y - 18 )° + y° = 180°

Step 2: Solve

6y° - 18° = 180°

Step 3:

6y° = 162°

Divide

y = 27°

Step 5: Equation 2

( 5 ( 27 ) - 18 )° + x° = 180°

Step 6: Solve

( 135 - 18 )° + x° = 180°

Step 7:

117° + x° = 180°

x = 63°

Hope This Helps :)

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
