It will be after 13 weeks.
Answer:
After 13 weeks, Vicki and Jeb will have the same number of baseball cards.
Step-by-step explanation:
Let n be the required number of weeks after which Vicki and Jeb have the same number of baseball cards.
The number of cards Vicki will buy after n weeks = 210 + 15n
The number of cards Jeb will buy after n weeks = 275 + 10n
Since, these are equal,
210 + 15n = 275 + 10n
15n - 10n = 275 - 210
5n = 65
Divide both sides by 5.
n = 13.
Hence, after 13 weeks, Vicki and Jeb will have the same number of baseball cards.

I am too lazy to do question 6 if u want the answer tell me
28 7/8, write 875/1000 and keep dividing by 5 to get the simplest form
The slope is 2/3 and the y intercept if you need it is -3
F(5)= 5^2+4(5) = 25+20=45
g(6)= 2(6)+2 = 14
f(5)+g(6) = 45+14 = 59
21√$42.84 ≈ 21√42.84=137.449773
Hope this helps~!
