Answer:
an=6+6(n-1)
Step-by-step explanation:
Since the circumference meaning the whole line is 22 centimeters long then the radius would be half of that...sooo....22/2=11. The radius for N is 11cm...hope it helps :)
Answer: she bought 13 petunias
Step-by-step explanation:
Let x represent the number of Petunias pot of flowers that she bought.
Let y represent the number of begonias pot of flowers that she bought.
She bought 22 potted plants. This means that
x + y = 22
Petunias cost $7 per pot and begonias cost $8 per pot. She spent a total of $163. This means that
7x + 8y = 163 - - - - - - - - - - - -1
Substituting x = 22 - y into equation 1, it becomes
7(22 - y) + 8y = 163
154 - 7y + 8y = 163
- 7y + 8y = 163 - 154
y = 9
x = 22 - y = 22 - 9
x = 13
...huh? I don’t really know what all those other letters and numbers are supposed to mean, but I’m fairly sure it’s the same as increasing by 198%.
For Example...
1. 100 • 1.98 = 198, and 100 • 198% = 198
2. 30 • 1.98 = 59.4, and 30 • 198% = 59.4
You could keep doing this for as many numbers as you want, and both the number and the percentage would give you the same answers. Feel free to check my math above if you want.
Anyways, 198% should be your answer. I hope this helps :)
