Question

Solve the equation or formula for the indicated variable.

A=213w, for w


Equation


A. w equals a over 21 cubed


B. w equals a over 21


C. w equals one cubed over 2a


D. w equals a over three minus two

Answer 1

A

Explanation:

given

A = 21³w

isolate w by dividing both sides by 21³

`(A)/(21^3)` =
`(21^3)/(21^3)` w , that is

w =
`(A)/(21^3)`
