Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
Answer:D because you divide it bu a common factor

Step-by-step explanation:
The approximate equation to convert from liters to quarts is : x • 1.056688.
We enter 65 for x and multiply.
65 • 1.056688 = 68.68472
We round that to the nearest 100th to get our final answer.
Our final answer: 68.68 liters
-x = -1. Anything “X” equals to the number One. So do Y = -1 + 1.
