y=sqrt((x+a)/-2b))

F=(5/9)C+32

Can't read the rest

Step-by-step explanation:

-2by^2=x+a

y^2=(x+a)/-2b

y=sqrt((x+a)/-2b))

F-32=(5/9)C

F=(5/9)C+32 (The actual Fahrenheit-Celcius formula)

NOTE: The other pictures cannot be opened.

Hi there! Im going to answer the subject of the formula x=a-2b^2

To find you need  to subtract the a to the negative 2 which is going to be -1

So the actual Fahrenheit-Celcius formula is F=(5/9)C+32

Hope this helps

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
