We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3

Anoki bought 360 millimeters of fabric. How many centimeters of fabric does Anoki have? It’s either 360, 36.0,3.60, or 0.360
Stels [109]
Hey!


First, we need to know how many millimeters are in a centimeter.

<em>10 mm = 1 cm</em>

Okay, now we can write an equation.

<em>360 mm ÷ 10</em>

To solve this equation, we simply divide.

<em>360 mm ÷ 10 = 36 cm</em>

<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters  <em>of fabric.</em>

Hope this helps!

Jon ate too many holiday cookies and gained 2.2 kilograms in December. Then he went on a diet and lost 1.5 kilograms in January.
gogolik [260]

Answer:

Jon lost a total of 3 kilograms in these 3 months.

Step-by-step explanation:

Weight that Jon gained in December = 2.2 kilograms

Weight that Jon lost in January = 1.5 kilograms

Weight that Jon lost in February = 3.7 kilograms

Overall Change in his weight = Total Weight he gained - Total weight he Lost

Total weight he gained is 2.2 kilograms as he only gained weight in December. Total weight he lost will be sum of weights he lost in January and February.

So, total weight Jon lost = 1.5 + 3.7 = 5.2 kilograms

Thus,

Total change in Jon's Weight = 2.2 - 5.2 = -3.0 kilograms

This shows that Jon lost a total of 3 kilograms in these 3 months.

Conclusion:

The statement that best describe the total change in his weight is: Jon lost a total of 3 kilograms in these 3 months

Which properties justify the steps taken to solve the system?
Nutka1998 [239]

Answer:

X=-1

Y=1

Step-by-step explanation:

6x-12y

-18

) 6x + 4y

-

-2

Subtract the two equations

6x - 12y - (6x + 4y) = -18 - (-2)

Determine the sign

6x- 12y - 6x- 4y

=-18 + 2

Simplify

-12y

- Ay

=-18 + 2

Solve the equation

Substitute

6×+4

-2

Solve the equation

A brand new filled can of chicken broth is 10 cm tall and has a radius of 10 cm. Mishka uses some of the broth to cook and now t
Maurinko [17]

we have chicken broth in cylindrical can.

we have given the height radius of cylindrical can.

h=10cm r=10 cm .

and she have 6cm broth height in the tin that means she had used 4 cm of height of broth .

now we need to find volume of two cylinder with h=10 cm and 6cm

and we need to find the difference between the volumes .

volume1=\pi *r*h_{1} =\pi *(10)^2*10=3.14*1000=3140 cm^3

volume 2=\pi *(10)^2*6=1884cm^3

volume used =volume 1-volume2=3140-1884=1256cm^3 is used
