F(x) stands for a function, and if x stands for the number of days, than she can do 225 per day, which would be the multiplication to find the toatl 225x.
Then, with 45 extra, we add that to the equation:
F(x) = 225x + 45
Answer: F(x) = 225x + 45

+ = <3

change

given you

making x the subject by transferring the -19 to the right hand side of the equation


dividing through by 5


{
}
also given

change the operation sign to =



dividing through by -4


so the truth set is
{x:x>9/4}.
The < sign changes to > because we divided by a negative number when solving for x
the radius is half of the diameter, so d = 2r , or double the radius :)
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
Answer: As a decimal it would be .136. You can write it as a decimal by dividing by 100 as you would need to get this total by multiplying by 100. Just reverse the steps into making a percentage.
Example: 70 out of 200.
You'd do 70 divided by 200 and get .35.
After, you would multiply by 100 to turn it into a percentage.
If you want to turn it into a decimal divide by 100.
