Apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
<u>Solution:</u>
Need to determine what operation is required to get one-tenth of a number and 10 times of a number
To get one tenth of a number, divide the number by 10.
For example to get one – tenth of 100, divide it by 10, we get 10 as a result.

To get ten times of a number, multiply the number by 10
For example 10 times of 10 = 10 x 10 = 100
Hence apply division by 10 when one tenth of a number is required and apply multiplication by 10 when 10 times of a number is required.
-5y=12-3x (subtract 3x from both sides)
y = - 12-3x/5 (divide both sides by -5)
y = - 3(4-x)/5 (common term is 3)
Answer: [-1/8, infinity) , {x | X greater than or equal to -1/8}
Step-by-step explanation:
Domain is what x can be. Thus, in the function f(x), we place limits such as x cannot make the square root a negative number because then it would not be a real number. Thus 8x+4-3 can be simplified to 8x+1. Setting this to 0, we get 8x+1=0 which solves out to x cannot equal -1/8. Thus, x can equal and be greater than -1/8.
Answer:
218
Step-by-step explanation:
this is ratio.
5+4=9. which is the ratio you add it.
5/9×360=200
therefore the number of boys in school during 2013 january is 200 plus admitted boys in February is 200+18=218.
therefore the number of boys in school from january to february is 218.
