Answer: scale factor = 1.5
Step-by-step explanation:

Given: Triangle ABC is a scaled copy of triangle DEF.
Side AB = 12 cm and is the longest side of ABC.
Side DE = 8 cm and is the longest side of DEF.

AB is corresponds DE (longest side of both triangles)
So, 
Hence, the scale factor = 1.5.
You are close, but it is not the correct answer.
1 + 2k = 5k + 7
First, since we are trying to get the variable by itself, we need to move all things to one side. Let's subtract 1 from each side.

Second, we can now subtract (7 - 1) to get 6. Let's add that into our problem and then subtract 5 from each side, still trying to get the variable by itself.

Third, subtract (2k - 5k) to get -3k. Hint the negative symbol now. If the problem were switched the other way, it would still be a positive.

Fourth, we can now divide each side by -3. This results in a fraction and also getting the variable by itself on one side of the problem. Remember the negative sign in front of the fraction since (-3) carried it.
Fifth, this is our last step. We need to simplify the fraction. Since out fraction is 6/3, which number multiples by 3 to get the answer of 6? The answer is 2, since (3 × 2 = 6). Don't forget the negative!

Step-by-step explanation:
to find the volume you multiply the length, width and height together.
An absolute value inequality that models this situation: 
The required compound inequality representing all possible weights for Mr. Bean.: 
<u>Given:</u> For the last 20 years,
Mr. Bean has weighed 120 pounds, give or take 4 pounds.
<u>To write</u>: a) An absolute value inequality that models this situation.
b) a compound inequality representing all possible weights for Mr. Bean.
<u>Computation:</u>
Let <em>x</em> be the actual weight of Mr. Bean,
then
Required absolute inequality:
It can be written as

Add 120 on all sides , we get
