Answer:
Step-by-step explanation:
Standard form is Ax + By = C, so we want x to be on the left side
To accomplish this, subtract 1/4x from both sides.
Multiply by -4 to get x to be equal to 1.
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
Answer:
25 ft
Step-by-step explanation:
You need to add 9+7+9.
There are two 9s and just one 7. 9+9 is 18 and 18+7 is 25
My best guess is a line graph because it shows the consistent numbers and then you can lay them all out after you have completed the graph
Answer:
A because you can go into the numbers evenly
