Question

Shane has a segment with endpoints C(3, 4) and D(11, 3) that is divided by a point E such that CE and DE form a 3:5 ratio. He knows that the distance between the x-coordinates is 8 units. Which of the following fractions will let him find the x-coordinate for point E?

3 over 5
5 over 3
3 over 8
5 over 8

Answer 1

@Er.Mohd.AMIR Thank you

Answer 2

thats incorrect, work thru the method and youll see why

Answer 3

if you are just going to accept any direct answer given to you, then you will find that you receive wrong answers more times than not.

Answer 4

@amistre64 Could you help me through it then?

Answer 5

sure

tell me what you know or think about it first, lets see what ideas you have to work with.

Answer 6

I think that the answer could be 3/8 but i am very confused

Answer 7

you are right, but the question itself is not well stated.

what is your reasoning for 3/8 ?

Answer 8

Because of the 3:5 ratio it would add it up too 8 total and E would fall at three. Does that make sense?

Answer 9

that makes perfect sense.

but i think your E=3 is off

let me dbl chk

we want to add 3 to the C x component; E x component is 3+3

@amistre64

Answer 11

now the thing is bad becuase, we can use 5/8 as well

8/8 = 1

5*1 = 5

subtracting from the right side: 11-5 = 6 is just as valid

Answer 12

so in my view, the question has 2 right answers.

Answer 13

Oh so its kind of a gamble then?

Answer 14

its a bad question if you can only pick one :)

they most likely want 3/8
