Y and X have a proportional relationship and Y equals five when X equals four what is the value of X when Y equals eight

1 answer:

7 0

I'm thinking that X would equal 7.
The proportion shown above says X=4 when Y=5. The relationship seems to be that Y is always one value more than X.
Hope this helps!

Points B, D, and F are midpoints if the sides of ACE. EC=38 and DF=16. Find AC

vekshin1

Answer:

AC=32 units.

Step by step explanation:

Given information: B, D, and F are midpoints if the sides of ΔACE, EC = 38 and DF = 16.

Consider the below figure attached with this question.

According to the midpoint theorem, if a line segments connecting two midpoints then the line is parallel to the third side and it's length is half of the third side.

Since F and D are midpoints of AE and EC respectively.

Using midpoint theorem, the length of AC is twice of DF.

$AC=2\times DF$
