I think your suppose to multiply it by 3 because 2*3is 6 and 6 times 3 is 18 then 18 times 3 is 54*3 is 162 and 162*3 is 486

3(x - 5) = 30<br> I dont know how to solve this

Anastaziya [24]

Answer:

x=15

Step-by-step explanation:

3(x-5)=30

First, you would distribute the three to the x and the negative five.

3x-15=30

Then you would add 15 to the 15 to cancel it and to the 30 to make it even.

3x-15=30

+15=+15=

3x=45

Finally, you would divide 3 into both sides, cancelling out the three and fiving you,

x=15

Hope this helped!

HELP PLEASE! ONLY 5 MORE MINUTES! Look at the following shape below: Please find the PERIMETER of the following shape using the

Evgen [1.6K]

Answer:

The perimeter is $P=73.12\ cm$

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the circumference of a semicircle

plus the perimeter of a square minus the diameter of the circle

$P=\pi r+4(b)-D$

we have

$r=8\ cm$

$b=16\ cm$

$D=16\ cm$

The diameter of the circle is equal to the length side of the square

substitute

$P=(3.14)(8)+4(16)-16$

$P=25.12+64-16$

$P=73.12\ cm$

Decide if Y=3x-9 and Y=4x-9 have many solutions, one solution, or no solutions.

Nuetrik [128]

Answer:

(0,-9)

Step-by-step explanation:

Well first we need to solve the rowing eqation by combining like terms and separating x.

$3x - 9 = 4x - 9$

So let’s do -3x

-9 = x -9

x = 0.

So if x is 0 we can plug that in one of the equations.

y = 4(0) - 9

y = -9

So the solution where the 2 lines meet is at (0,-9)

For more proof look at the image below.
