<span>Krystal's rate = 1 floor in 16 min. = 1/16 floors per min.
Working together their rate = 1 floor in 5.76 min. = 1/5.76 floors per min.
We need to determine Perry's rate, so we need to equate their combined rate with the sum of the individual rates.
Let Perry's time = x
In equation form, we can write:
1/16 + 1/x = 1/5.76
Solve for x:
(x+16)/16x = 1/5.76 -> 5.76(x+16) = 16x -> 10.24x = 92.16 -> x = 9
So, Perry would take 9 mins. to do the floor alone.
I hope this helped!

answer:
bubble gum costs $0.15 and fudge costs $1.05
Step-by-step explanation:
you want to set up a systems of equation.
call cost of fudge "f' and call cost of bubble gum "b". Chase's purchase proves 5.70=5f+3b. Sara's purchase tells us that 3.60=2f+10b. you can solve with substitution or elimination
The mean is the unit of center that may be used to predict how many strokes will be needed to complete the ninth hole.
The data is almost symmetrical, making the mean the best option.
What is symmetrical data?
- Asymmetric communications refers to any system where, when averaged over time, the data speed or amount is different in one direction from the other.
- Asymmetry is defined as the lack of precise similarity between two pieces.
- A fiddler crab's body is asymmetrical, as evidenced by the fact that one of its claws is larger than the other.
- Absence of a standard unit of measurement between two things or amounts; incomprehensibility.
So the more about symmetrical visit.

Answer:
Option C
Step-by-step explanation:
All of these equation have a slope of x=-3, as this is the only number that will be acompanied by an x (the slope of a function is the number on the equation that has an X). To know which one of this equations passes through the points (7;-2) we can supplant these numbers on each equation until the result at both sides are equals.
The correct answer is the option c, because if we supplant these numbers (x=7 and y=-2) on the equation, we get an equality.
