It's easiest to start with the point-slope form of an equation,
, where m is the slope and
is the point given.
We have m = 3,
, and
.
We plug in these values to get
.
We now rearrange to get this into slope-intercept form,
, by solving for y.
I think the answer ia A that what i think
It will take 7.666666667 hours ( or so ) to travel from Boston to Washington, so if he leaves at 7:30 he will arrive at ( not including the decimal ) 2:30 pm.
Hope this helps, if not, comment below please!!!
Answer:
25/64
Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
Speed is expressed as the ratio of distance/time = d/t
in Alex's case, speed = (3.8 miles / 18 minutes)
. . . or simply
3.8/18
