Answer:

1/7 + 2 4/7 = 2 5/7

Step-by-step explanation:

Leave 2 alone since there are no other whole numbers to add to it.

Then combine the fractions

1/7 + 4/7 = 5/7

So we have 2 5/7

BD and AC are chords that intersect at point Y.

Sindrei [870]

Answer:

4 units

Step-by-step explanation:

The complete question is

BD and AC are chords that intersect at point Y. A circle is shown. Chords B D and A C intersect at point Y. The length of B Y is 3, the length of Y D is 8, the length of A Y is x, and the length of Y C is 6. What is the length of line segment AY?

The picture of the question in the attached figure

we know that

The Intersecting Chord Theorem states that: When two chords intersect each other inside a circle,the products of their segments are equal.

In this problem

$(BY)(YD)=(AY)(YC)$

substitute the given values

$(3)(8)=(x)(6)$

solve for x

$24=6x\\x=24/6\\x=4\ units$

therefore

The length of segment AY is 4 units
