I know this for sure that it's not an enlargement bc 4 is not bigger than 5 and u can do 4 divided by 5 which equals 0.8.And remember this 1 is an isometric. And I think that if it's less than 1 it's a reduction and if it's more than 1 its an enlargement. So 4 over 5 is a REDUCTION. <<<<<< that's the correct answer and also u better give me thanks -.- Please :)
Answer: The number of red tiles = 15.
Step-by-step explanation:
Let the number of red tiles be x, and the total tiles be y.
Since, the pattern he used equal numbers of red white tiles, therefore the number of white tiles = x
The number of blue tiles = 20
Forty percent of the pattern was made of blue tiles and 40%=0.40
Therefore,
Now, the total number of tiles = 
The number of red tiles = 15.
We have the equation of the line as follows:
y = 0.5x + 79
We want to calculate the melting point (the y value) of DNA with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees

<h3>1.) Subtract 14 from both sides:</h3>
Cancels Out
<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>
<u>Equation at the end of Step 1: </u>
÷ 
<h3>2.) Multiply both sides by −0.8:</h3>

Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)
