Answer:
2x - 2 = 14
Step-by-step explanation:
Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2
So then
x + x - 2 = 14
2x - 2 = 14
You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:
2x = 14 + 2
2x = 16
x = 8
So Fran has 8 hats and Elena has 6 hats.

Number 1 would be the correct answer :)
Use distance formula d=sqrt root (y2-y1)^2+(x2-x1)^2. So (-3, 4) and (1, 7). D= sqrt root ( 7-4)^2+(-3+1)^2. So now solve d= sqrt (3)^2+(-2)^2. Now d= sqrt 9+4. D= sqrt 13 or 3.60555
Let the number of times she turns the pedal in one mile be x.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

Therefore, she turns the pedal 500 times in one mile.
