Answer:

x = -2.4

Step-by-step explanation:

12x -4 = 17x +8

-12x -12x

That's to get all the x-values on one side so we can solve for x.

-4 = 5x +8

-8 -8

-12 = 5x

But now we need to find what 1 x value is equal to so we divide,

-12/5 and 5x/5 to get -2.4 = x

Hope that helps and have a great day!

igor_vitrenko [27]

Answer:

$Cost=\$3.66234\approx \$3.67$

Step-by-step explanation:

$Height\ of\ tub=3\ feet\\\\Length\ of\ tub=6\ feet\\\\width\ of\ tub=5\ feet\\\\Volume=Length\times Width\times Height\\\\Volume=6\times 5\times 3=90\ feet^3$

$1\ feet^3=7.48052\ gallons\\\\90\ feet^3=90\times 7.48052=673.2468\ gallons$

$cost\ of\ 1000\ gallons=\$5\\\\cost\ of\ 1\ gallons=\$ \frac{5}{1000}\\\\cost\ of\ 673.2468\ gallons=\$ \frac{5}{1000}\times 673.2468=\$3.366234$
