Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
I the median is a number that’s always suppose to be used on a dot plot because the median always ask for all kind of numbers to be put in a dot plot and the mean has a bit less number and their odd ;)
I just studied this !!
6 + 2 = 12
When 2 = 3
Change the equation to: 6 + 3
So,
6 + 3 = 9
You're answer is 9
I need points bro, so imma just type this rq cuz I’m mid test thank u tho
4+4x=20
-4. -4
4x=16
X=4 (hope this helps)
