Answer:
Part A: Kimberly
Part B:
Becca = 22.5 miles, Kimberly = 25 miles
Step-by-step explanation:
Part A:
Given that Becca runs at a constant speed of 4.5 miles per hour, use the table to find the constant speed that Kimberly runs, and compare who runs faster.
Let x = time
y = distance
k = speed = y/x
Equation for each person can be written as: y = kx
Therefore:
✔️Equation for Becca if k = 4.5
y = 4.5x
✔️Find k (speed) of Kimberly using (2, 10):
Speed (k) = y/x
k = 10/2
k = 5 miles per hour
Equation for Kimberly would be:
y = 5x
Comparing their speed, Kimberly runs faster because she covers more miles per hour than Becca does.
Part B:
For Becca, substitute x = 5 into Becca's equation, y = 4.5x
Thus:
y = 4.5*5 = 22.5 miles
For Kimberly, substitute x = 5 into Kimberly's equation, y = 5x
Thus:
y = 5*5 = 25 miles

Answer:
14
Step-by-step explanation:
We can find the sum of these numbers by adding them together.
The cumulative rule of addition lets us add numbers together in any order we want.
So, for 2 + 3 + 4 + 5 …
2 + 3 = 5
So now we have 5 + 4 + 5
5 + 4 = 9
Now we have 9 + 5
And 9 + 5 = 14
So, your answer is 14
Hope this helps!
Answer:
6.48%
Step-by-step explanation:
t - c = b
t = 31.93
c = 29.99
b = 31.93 - 29.99
b = 6.48%
