Answer:

x=1 or x=1/2

Step-by-step explanation:

9x^2 - 12x +3

9x^2 -(9+3)x+3

9x^2-9x-3x+3

9x(x-1)-3(x-1)

(x-1)(9x-3)

so,

either x-1=0

x=1

or

9x-3=0

9x=3

x=3/9

x=1/2

REY [17]

The purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

What is the mean ? i don’t need work but it could help
lapo4ka [179]

Answer:

The median is the middle number; found by ordering all data points and picking out the one in the middle.

You want to put the numbers in order:

47, 49, 49, 50, 52, 57, 57, 57, 61

Then you go one number at a time from both ends until you get into the middle:

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

47, 49, 49, 50, 52, 57, 57, 57, 61

So the answer is 52.

Tip: when you do this and you are left with two numbers that are in the middle, add them and divide them by 2.
