THIS IS MY 4TH TIME POSTING THIS (I did it on my other account )Abby has just started training for a marathon. She ran 15 miles in total during her first week of training. She wants to add an additional 2 miles to her weekly total during each subsequent week. Write an explicit rule for the arithmetic sequence that represents this situation, and use it to find how many miles Abby will run during her twelfth week of training. Please show work for full credit

She will run 202 miles in 12 wks.

Step-by-step explanation:

y = 17x + 15

15 represents the # of miles she ran in the first week.

17 represents the amount of miles she will run each week

x represents the # of weeks

y = the total # of miles in 12 weeks.

To solve plug in 11 for x since she ran 15 miles the first week she has 11 more to go.

y = 17(11) + 15

y = 187 + 15

y = 202

Hope this helps!

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation
