What does x equal in the equation − 6 x − 15 = 4 x + 35?

x = -5

Step-by-step explanation:

− 6 x − 15 = 4 x + 35

Add 6x to each side

− 6 x+6x  − 15 = 4 x+6x + 35

-15 = 10x+35

Subtract 35 from each side

-15-35 = 10x+35-35

-50 = 10x

Divide each side by 10

-50/10 = 10x/10

-5 =x

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
