No because if you multiply a positive times a negative you will just get a negative and 7 isn't an negative so no.

In order to figure this out, you must solve the equation.

1-6x=7 (given)

-6x=6 (subtract 1 from both sides)

X=-1 (divide both sides by -6)

The answer is no.

Container A has radius r and height h . It holds a maximum of 44 ounces of water. Container B has radius 2.5r and height 4h .

Dennis_Churaev [7]

Set an equation:

$\pi r^{2} h$ =44
divide both sides by 3.14
$r^{2} h$ =14

$\pi (2.5r)^{2} 4h=x$
divide both sides by 6.25, 4, and 3.14
$r^{2} h$ =x/78.5

Since these two equations are equal, we can set them up that way.

x/78.5=14
multiply both sides by 78.5
x=1099

Answer: The maximum amount of water that container B can hold is 1,099 ounces.
