Answer: Irrational

Explanation:

Based on what is shown so far, there isn't any clear pattern of the digits. And the digits don't seem to repeat. Because of this, it's very likely that the number is irrational.

If in contrast we had something like 0.47474747, where the "47"s repeat forever", then it would be rational. We would be able to use algebra to show that 47/99 = 0.4747474747...

$11.\\3d-2(8d-9)=-2d-4\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\3d+(-2)(8d)+(-2)(-9)=-2d-4\\\\3d-16d+18=-2d-4\qquad\text{combine like terms}\\\\(3d-16d)+18=-2d-4\qquad\text{subtract 18 from both sides}\\\\-13d=-2d-22\qquad\text{add 2d to both sides}\\\\-11d=-22\qquad\text{divide both sides by (-11)}\\\\\boxed{d=2}$

$13.\\3x-6=2+4(x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\3x-6=2+(4)(x)+(4)(-2)\\\\3x-6=2+4x-8\qquad\text{combine like terms}\\\\3x-6=4x+(2-8)\\\\3x-6=4x-6\qquad\text{add 6 to both sides}\\\\3x=4x\qquad\text{subtract 3x from both sides}\\\\\boxed{x=0}$

$15.\\2(x-3)=3(2x+2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\(2)(x)+(2)(-3)=(3)(2x)+(3)(2)\\\\2x-6=6x+6\qquad\text{add 6 to both sides}\\\\2x=6x+12\qquad\text{subtract 6x from both sides}\\\\-4x=12\qquad\text{divide both sides by (-4)}\\\\\boxed{x=-3}$

$17.\\3b+4-12b+6+2b\qquad\text{combine like terms}\\\\=(3b-12b+2b)+(4+6)\\\\=\boxed{-7b+10}$
