Answer:
209.615384
Step-by-step explanation:
Ken spent $2.37 on groceries and $0.35 on candy, and paid for them with a 5 dollar bill.
To find how much money Ken spent, we add up how much he spent on groceries and candy
Total amount spent = 2.37+0.35= $2.72
Since he paid with a 5 dollar bill, we need to subtract it from how much he spent to find the change
Change = 5 - 2.72 = $2.28
Ken got $2.28 in change.
To fill the boxes, it would be

Answer:
all real numbers except ±5.
Step-by-step explanation:
Each function (f(x), g(x)) has a domain that is all real numbers. Their quotient (f(x)/g(x)) must exclude values that make g(x) = 0. The quotient is undefined when the denominator is zero. Those excluded values are x = ±5.
The domain of (f/g)(x) is all real numbers except ±5.
___
Of course you recognize x^2 -25 = 0 has solutions x = ±√25 = ±5. You can get there two ways:
- add 25 and take the square root: x^2=25; x=±√25.
- factor the difference of squares and set the factors to zero: (x-5)(x+5)=0 has solutions x-5=0 and x+5=0, that is, x = ±5.
