T varies inversely with the cube of W. When W is 3, T is 1/9. Find the value of W when T is 1/243

Lera25 [3.4K]

T varies inversely with the cube of W

$T = k/W^3$

$\frac{1}{9} = k/3^3$

$k = \dfrac{3^3}{9} = 3$

$W^3 = k/T$

$W = \sqrt[3]{ k/T }$

When $T=1/243$

$W = \sqrt[3]{ 3/(1/243)}= \sqrt[3]{729} = 9$

2(4x+2)=4x−12(x−1)2(4x+2)=4x−12(x−1)

Liula [17]

2(4x + 2) = 4x - 12(x - 1) |use distributive property: a(b +/- c) = ab +/- ac

8x + 4 = 4x - 12x + 12

8x + 4 = -8x + 12 |subtract 4 from both sides

8x = -8x + 8 |add 8x to both sides

16x = 8 |divide both sides by 16

x = 0.5
