4 0

Answer:

-6/7.

Step-by-step explanation:

-1/2 w -3/5 = 1/5w

-1/2 w - 1/5 w = 3/5

Multiply through by 10:

-5w - 2w = 6

-7w = 6

w = -6/7.

A = 1 4 π d 2 what is the formula to calculate the diameter of a circle
Anestetic [448]

Answer:

D=2\sqrt{\frac{A}{\pi}}

Step-by-step explanation:

we know that

The area of the circle is equal to

A=\frac{1}{4}\pi D^{2}

where

D is the diameter of the circle

Solve for D

That means-----> Isolate the variable D

Multiply both sides by 4 to remove the fraction

4A=\pi D^{2}

Divide both sides by π

\frac{4A}{\pi}=D^2

square root both sides

\sqrt{\frac{4A}{\pi}}=D

Rewrite

D=\sqrt{\frac{4A}{\pi}}

Simplify

D=2\sqrt{\frac{A}{\pi}}
