Complimentary angles add up to 90 degrees
AEC and CED are complimentary
Im not sure about the given data but I plotted the scatter plot based on what I understand on how the data should be presented.
Time (years)
3, 6, 9, 12, 15, 18, 21, 24
Number of participants(x1000)
22, 25, 28, 14, 17, 20,15, 9
Attached is the scatter plot created online.
x = time (years)
y = number of participantep explanation
Answer: $26.98
Step-by-step explanation:
1. You have the following information given in the problem above:
- Lou filled the tank with gas that cost $3.80 per gallon.
- Lou's car had 5.9 gallons in the 13-gallon tank.
2. Therefore, if he filled the tank, you can calculate the total amount of money Lou spent, by subtracting 13 gallons and 5.9 gallons and multiplying the result by $3.80.
3. Then, the result is:

16 goes into 75 4 times, with a remainder of 11.
75/16 = 4.6875
4 x 16 = 64
75 - 64 = 11

Step-by-step explanation:
Hi,
Store A: y = 9p
Store B: y = 9p + 5
Store C: y = p + 5
Store D: y = p + f
Second Part:
Store A: T = 9n
Store B: T = 9n + 5
Store C: T = n + 5
Store D: T = p + f
I hope this helps :)
