The price, s, of a mountain bike at speed cycling is $290 less than twice the price, d, of the same bike at downhill racing. the difference in price between the bike at speed cycling and downhill racing is $304. which system of equations can be used to determine the price of the bike at each store?
s - 2d = -290
s - d = -304

2s - d = 290
s - d = -304

2s - 2d = 290
s - d = -304

s - 2d = -290
s - d = 304

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
