38.=721.8 it's really just a matter of multiplication. I only have he answer for this one but, y'know, work and whatnot. If you would multiply 3 by 3 than wou would do the same for this problem
The answer is 6.87704918
6.9 rounding to the tenth
6.88rounding to the hundredth
6.877rounding to the thousandth <span />
That would be 4 and 5/8. Because you would find the common denominator which would be 8 and then take 2*4 and 2*1 and get 2/8 and then subtract 3 and 2/8 from 7 and 7/8 and get 4 and 5/8. I hope this helps you.
Y = x + 2 is closest to what I believe is the solution.
If the club begins with 2 members, then +2 MUST appear in the formula.
If the club adds 2 members every week, then the total number of members would be
f(x) = y = 2 + 2(x-1), where x is the number of weeks.
Test this: If x = 1, then y = 2+2(1-1) = 2 + 0 = 2. This is correct. The club began with 2 members in week 1
