help plz

OpenStudy (anonymous):

Giovanna can ride her bike 1.5 mi every 5 min. How many miles can she ride her bike in 24 min? miles

OpenStudy (anonymous):

\[\frac{ 1.5 }{ 5 }=\frac{ ? }{ 24 }\] Can you solve it now?

OpenStudy (anonymous):

umm not really

OpenStudy (anonymous):

Because 24 is in the denominator, multiply both side by 24

OpenStudy (anonymous):

120

OpenStudy (anonymous):

huh

OpenStudy (anonymous):

So ? = 1.5x24/5

OpenStudy (anonymous):

7.2

OpenStudy (anonymous):

Right

OpenStudy (anonymous):

Well done

OpenStudy (anonymous):

i have more can i put them up

OpenStudy (anonymous):

OpenStudy (anonymous):

there it is

OpenStudy (anonymous):

Your answer?

OpenStudy (anonymous):

this is the one i dont know how to do at all

OpenStudy (anonymous):

Can you see the similarities in these values?

OpenStudy (anonymous):

oh yes times 3

OpenStudy (anonymous):

is that the answer

OpenStudy (anonymous):

Yeah. That's it. Depend on how you choose the graph, the slope can be 3 or 1/3

OpenStudy (anonymous):

one more

OpenStudy (anonymous):

Yes?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

OpenStudy (anonymous):

u get it

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

What are they? I am ready

OpenStudy (anonymous):

ok ima put it up

OpenStudy (anonymous):

OpenStudy (anonymous):

there it is

OpenStudy (anonymous):

\[slope=\frac{ rise }{ run }\] What do you think?

OpenStudy (anonymous):

idk

OpenStudy (anonymous):

Well when x runs from 6 to 18, y rises from 2 to 6. So \[Slope=\frac{ 12 }{ 4 }=3\]

OpenStudy (anonymous):

oh thx

OpenStudy (anonymous):

No problem

OpenStudy (anonymous):

ima put next up ok

OpenStudy (anonymous):

Sure.

OpenStudy (anonymous):

OpenStudy (anonymous):

there it is u get is

OpenStudy (anonymous):

How about taking the y of the first and the y of the second coordinate then form (x,y) For example, (3,2) and (6,4) --> (6,2)

OpenStudy (anonymous):

so i subtract

OpenStudy (anonymous):

i need the answers and then u can explain it plz

OpenStudy (anonymous):

No take y of the first one, which is 2. Then take x of the second one, which is 6 x = 6, y = 2 ---> (6,2)

OpenStudy (anonymous):

huh how for the first one 3,2 and 6,4

OpenStudy (anonymous):

how would u find the answer

OpenStudy (anonymous):

The way I did, I think the answer for the first one is C. (6,2)

OpenStudy (anonymous):

how
