Step-by-step explanation:

3*3=9

Answer:

hello,I'll edit the process and say step by step.

result= 28x-30= -70x²+73x-18 = -5x+2

Sorry, it was a little long process. I could not explain them all. I said the result directly.And I am Turkish, sorry if there is a problem with my pronunciation.But remember, you will do it according to the distribution in the parenthesis.

Answer:

a . 45

Step-by-step explanation:

you can see the 20 is that small so you need to put 1/2 more of the 20 degrees angle to get the equation

Answer:

x = 4/5

Step-by-step explanation:

3(x-4)=12x

3x-12=12x

3x+12x-12=12x-12x

15x-12=0

15x-12+12=0+12

15x=12

15x/15=12/15

x = 4/5

hope it's helpful ❤❤❤❤

THANK YOU.

Answer:

x<100

Step-by-step explanation:

The given equation is :

x-19<81

Adding 19 to both sides of the equation.

x-19+19<81+19

x<100

It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.

Answer:

negative chargedhhdhd

Answer:

25% Or

1/4 Or

0.25

Step-by-step explanation:

Solve:

200 divided by 50 is 4

Check your math:

50*4= 200

Your only counting a single piece of this whole. This can be written in 3 ways, 25%, 1/4, or 0.25.

Hope this helps!

Answer:50%

% of brass players=50/200 x 100

Answer:

1800in

Step-by-step explanation:

3ft=1yd

3x50=150ft

12in=1ft

12x150=1800in

Answer:

Step-by-step explanation:

1 yard = 36 inches

50 yards = 36 x 50 = 1800 inches

Answer:

p = - 8

Step-by-step explanation:

3 (p - 1) = 2p - 11

3p - 3 = 2p - 11

3p - 2p = -11 + 3

p = -8

Answer:

p = - 8

Step-by-step explanation:

Given

3(p - 1) = 2p - 11 ← distribute parenthesis on left side

3p - 3 = 2p - 11 ( subtract 2p from both sides )

p - 3 = - 11 ( add 3 to both sides )

p = - 8

Answer:

45

Step-by-step explanation:

This might not work every time but it does this time.

99(25/55)=45

45

Answer:

z = 44

Step-by-step explanation:

180 - (44+52) = 180 - 96 = 84º

180 - 84 = 96º

180 - (96 + 40) = z

     180 - 136 = z

     z = 44

Answer:

I have made it in above picture

it is option A

Answer:

x=16

Step-by-step explanation:

when solving for a variable, get the variables to one side of the equation and the numbers to the other side.

3+2x=41

*minus 3 from both sides of the equation to get rid of the number on the side of variables of the equation*

2x=38

to get one variable alone, divide the whole equation by 2

x=16

Answer:

8z+5

Step-by-step explanation:

Let's split the expression into two terms- z and... not z :)

3z+5z=8z

Why? it's just 3+5 with z tacked on the end

14-9=5

simple math :)

put it together to get

8z+5

all done!

lmk if you have any more questions

Answer: A

Step-by-step explanation:

Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.

First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical

[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]

The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.

[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]

The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

Answer:

43

Step-by-step explanation:

[tex]3^{3}[/tex]+[tex]4^{2}[/tex]=

Solve:

[tex]3^{3}[/tex]= 3*3*3= 9*3= 27

[tex]4^{2}[/tex]= 4*4= 16

Then add them together:

27+16= 43

Hope this helps!

Answer:

a- 2 8/27

Step-by-step explanation:

Answer:

[tex]2\frac{8}{27}[/tex]

Step-by-step explanation:

Answer:

$29.25

Step-by-step explanation:

The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

(y+4)(3y−5)=0

Step 1: Simplify both sides of the equation.

3y2+7y−20=0

Step 2: Factor left side of equation.

(3y−5)(y+4)=0

Step 3: Set factors equal to 0.

3y−5=0 or y+4=0

y=5 /3

or y=−4

Answer:

very specific...sus...yea no one knows

Step-by-step explanation:

In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .
