Answer:

11

Step-by-step explanation:

Givens:

AD = 8

AC = 4y - 28

y = ?

First we can see that AD and DC are equal.

-note AD and AC are not equal

But 2 times the length of AD should give you AC so.....

2 x length of AD = 16 = AC

We can use the equation:

16 = 4y - 28

Solve for y

16 + 28 = 4y

44 = 4y

y = 11

Therefore value of y is 11.

Answer:

True

Step-by-step explanation:

Let's see if it is true....

                  1/2 ÷ 3

Rewritten,

                =1/2 ÷ 3/1

(All numbers have a denominator of 1)

Therefore, the original statement  1/2 ÷ 3 = 1/6  is true!

Now the model is in the link below!

Hope this helps!

The following two right triangles are similar.If side PQ = 42, side LM = 28, and side QR = 24, what is the length of side MN?
barxatty [35]
16. i’m pretty sure cause the ratio would be 42/24 28/x if you divide PQ by LM, the answer is the same number you would use to divide LM to get MN and finish your ratios
