Answers:
- Zainab made more money
- She made $2.50 more
=======================================================
Explanation:
To find the hourly rate, we divide the money made over the number of hours.
- Zainab's hourly rate = 44/8 = $5.50 per hour
- Keziah's hourly rate = 47.25/9 = $5.25 per hour
Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours
- Zainab: 5.50*10 = 55 dollars
- Keziah: 5.25*10 = 52.50 dollars
We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.
Answer:
603
Step-by-step explanation:
The rate of change is found by
rate of change = f(b) -f(a)
------------
b-a
We need to find the rate of change for the interval 7,9 and 4,6
We know b= 9 and a = 7
f(9) -f(7)
------------
9-7
3878-1852

We know b= 6 and a = 4
f(6) -f(4)

X intercept is 3,0
Y intercept is 0,3
Slope is -1
The number is 16
16/4 = 4
16 - 12 = 4 (true)
your number is 16 hope this helps
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
Hope this helps!
