For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
Answer:
the equation that will help find the time it takes chelsea to get to school on the bus is:
45 * t = 2.5 * (1-t)
Note: the equation will have one solution.
Answer:
<u>Option B. 11</u>
Step-by-step explanation:
See the attached figure
As the figure about an ellipse
So, The sum of distance between A and the foci will be equal the major axis
AB = 6 and the major axis = 17
∴ AB + AC = major axis
∴ 6 + AC = 17
∴ AC = 17 - 6 = 11
<u>So, the length of the blue line segment = 11</u>
Answer:
x=13/8
Step-by-step explanation:
8x-12=1
8x=13
x=13/8
he change 3/4 instead of 5/7
The increase is 1150 ... 11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.
