What is the length of DE?? Thx :)

Alex

Answer:

10

Step-by-step explanation:

Your scale factor is 3/2, because when you compare AC and DF, the ration is 18/12, or 3/2. We can set up a proportion:

3/2=15/x

We cross multiplu

3x=30

x=10

So, the length of DE is 10 units.

Solve for y, z, x or t: y+ y/a =b, if a≠−1

Vadim26 [7]

Answer:

$y=ab/(a+1)$

Explanation:

In this case, you need to solve for y in y + y/a = b, if s ≠ - 1.

This is how you do it step-by-step:

<u>1. Multiply all the equation by the common denominator</u>: a

$y + y/a = b\\ \\ a(y + y/a = b)\\ \\ a(y + y/a) = ab$

<u>2. Simplify</u>:

$ay + ay/a = ab\\ \\ ay+y=ab$

<u>3. Common factor:</u> y

$y(a+1)=ab$

<u>4. Divide both sides by a + 1</u>

$y=ab/(a+1)$
