oh ok thanks thats helpful

Answer 11

the info `A ramp for wheelchair access to the gym has a slope of 5% (that is, the ramp rises 5 feet vertically for every 100 feet of horizontal distance)` basically tells us that we'll have this proportion

2/x = 5/100

Answer 12

the numerators represent the vertical change in distance
the denomiators represent the horizontal change in distance

Answer 13

ok

Answer 14

so you see how I got 2/x = 5/100? if so, then the next step is to isolate x

Answer 15

yep, I got that

Answer 16

ok tell me what x is

Answer 17

40

Answer 18

good

Answer 19

so thats the answer and how we do it?

Answer 20

like I said, solving 2/x = 5/100 for x

Answer 21

ok, thanks! I have another question! can i tag you in a new question and help me?

Answer 22

2/x = 5/100

2*100 = x*5 ... cross multiply

200 = 5x

5x = 200

5x/5 = 200/5 ... dividing both sides by 5

x = 40

Answer 23

ok! Can i make a new question and tag you in it?

Answer 24

sure
