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:

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: 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:

1.75 as a decimal or 1 3/4 as a mixed number

Perimeter is the sum of all 4 walls.

Divide the perimeter in half for the total of the width  + the length:

26/2 = 13 meters

Subtract the difference in length:

13 - 3 = 10

Divide by 2 walls:

10/2 = 5

The width is 5 metes.

The length is the 5 metes + the 3 meter difference = 5 +3 = 8 meters.

The length is 8 meters and the width is 5 meters.

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:

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 .

Correct option is B

Answer:

86+18[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Use the properties of 45-45-90 triangles to get a side length of 18 for the 2 legs of the isosceles triangle. Then add 43+18, which is the shorter length of the rectangle, +25, which is the longer edge, +18[tex]\sqrt{2}[/tex]. The answer is now 86+18[tex]\sqrt{2}[/tex].

Answer:

111.4556

Step-by-step explanation:

Perimeter = 18 + 25 + 18√2 + 43

Perimeter = 86 + 18√2

Perimeter = 86 + 18(1.4142)

Perimeter = 86 + 25.4556

Perimeter = 111.4556

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:

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

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
