you multiply boh sides by the other denomonater

Let's actually find the line of best fit...
m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)
m=(11*836-130*55)/(11*385-3025)
m=2046/1210
m=93/55
b=(Σy-93Σx/55)/n
b=(55Σy-93Σx)/(55n)
b=(7150-5115)/(55*11)
b=185/55, so the line of best fit is:
y=(93x+185)/55
A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.
Which means that those who do not practice at all will win about 3.36 times
B) y(13)=(93x+185)/55
y(13)≈25.34
So after 13 months of practice one would expect to win about 25.34 times.
Good Afternoon,
Okay so we have 15 hours already, now we need to add 60 minutes, which is exactly an hour.
So, 15 Hours + 1 Hour = 16 Hours.
16 Hours is your answer, I hope I helped and good luck studying!
Thank you,
Darian D.
