PLEASE HELP‼ Select the correct answer.
The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the y-variable, and what is the solution for this system?

x + 3y = 42
2x − y = 14

A. Multiply the second equation by -3. The solution is x = 12, y = 9.

B. Multiply the second equation by -2. The solution is x = 12, y = 10.

C. Multiply the second equation by 2. The solution is x = 15, y = 9.

D. Multiply the second equation by 3. The solution is x = 12, y = 10.

hey my pc broke down

Step-by-step explanation:

it unsinstalled windows

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
