Answer:

5x + 6

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

A is equal to 5d-5

I just went through all eh choices

It can’t be b or c becuase when distributed, it automatically is -5d+25 or vice versa with a different sign so their out

D is impossible becuase you can’t jsut flip a subtraction problem

And A is possible because adding a negative basically means subtracting so if flipped The signs have to change

Answer:

Step-by-step explanation:

Simplifying

5(4x + p) = w

Reorder the terms:

5(p + 4x) = w

(p * 5 + 4x * 5) = w

(5p + 20x) = w

Solving

5p + 20x = w

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-20x' to each side of the equation.

5p + 20x + -20x = w + -20x

Combine like terms: 20x + -20x = 0

5p + 0 = w + -20x

5p = w + -20x

Divide each side by '5'.

p = 0.2w + -4x

Simplifying

p = 0.2w + -4x

Answer:

The 1st and the 3rd one

Step-by-step explanation:

2.3+(-2.3) ➡ 2.3 -2.3 = 0 ,so this option is correct

-3.7+(-4.1) ➡ -3.7 - 4.1 = -7.8 so this option isn't correct

-2.6-(-12/4) ➡-2.6 + 3 = 0.4 this option is also correct

(5/2)+(-2.5) ➡ 5/2 -5/2 = 0 this  would be undefined because we can't divide 0 by 2 or any other rational numbers

E.72-(-100) ➡72+100= 172  this option is incorrect because 172 is positive

Answer:

d = 101

Step-by-step explanation:

t = 11

11 x 11 = 121

-20 + 121 = 101

check: 101- 121 = -20 (correct)

Answer:

I believe the measure of the sum of interior angles of  square is 360 degrees, and we know that all the angles are equal to 3x. You'd set up the equation to look like 3x+3x+3x+3x=360

simplify that, and you get 12x=360

this means x= 30

last one is the answer:D. X=12 and X=1

step by step:

d=b2-4ac=169-48=121

x1=(-b+√d)2a=(13+11)2=12

x2=(-b-√d)2a=(13-11)/2=1

X1=12 and X2=1

Answer:

It's 398

Step-by-step explanation.

Diameter of 8.

height of 12.

8 - .75 - .75= 6.5

6.5/2 = 3.25

3.25 x 3.25 x 12 x 3.14 = 397.995

round to the nearest whole number and you get

398

Take the diameter (8) an subtract is by both sides of the walls (0.75 each wall) that gives you 6.5. Take that 6.5 and half that, because you need to have the radius to solve volume problems, giving you 3.25.  Then multiply 3.25 by 3.25 together ( I know it seems redundant but it just works easier this way) This gives you 10.5625. After that take 10.5625 then multiply it into 12, being the height, which gives you 126.75. Finally take 126.75 and multiply that into 3.14 (pie) giving you the answer.

The approximate inside volume of the pipe is 398 cubic inches.

We must use the Volume formula for a right Cylinder to calculate the approximate Inside Volume of the pipe, which is described below:

[tex]V = \pi \cdot (r-t)^{2}\cdot h[/tex] (1)

Where:

[tex]V[/tex] - Inside volume, in cubic inches.

[tex]r[/tex] - Radius of the iron pipe, in inches.

[tex]t[/tex] - Wall thickness of the iron pipe, in inches.

[tex]h[/tex] - Height of the cylinder, in inches.

If we know that [tex]r = 4\,in[/tex], [tex]t = 0.75\,in[/tex] and [tex]h = 12\,in[/tex], then the approximate inside volume of the pipe:

[tex]V = \pi\cdot (4\,in-0.75\,in)^{2}\cdot (12\,in)[/tex]

[tex]V \approx 398.197\,in^{3}[/tex]

The approximate inside volume of the pipe is 398 cubic inches.

or 1/823543

Step-by-step explanation:

Answer:

XZ = 36 cm, BC = 12 cm

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{XZ}{AC}[/tex] = [tex]\frac{XY}{AB}[/tex] , substitute values

[tex]\frac{XZ}{9}[/tex] = [tex]\frac{16}{4}[/tex] = 4 ( multiply both sides by 9 )

XZ = 36 cm

and

[tex]\frac{BC}{YZ}[/tex] = [tex]\frac{AB}{XY}[/tex]

[tex]\frac{BC}{48}[/tex] = [tex]\frac{4}{16}[/tex] ( cross- multiply )

16BC = 192 ( divide both sides by 16 )

BC = 12 cm

Answer:

See Below.

Step-by-step explanation:

In the given figure, AP = BP = PC.

And we want to prove that ∠ABC is a right angle.

Since AP = BP and BP = PC, we can create two isosceles triangles: ΔAPB and ΔCPB.

By the definition of isosceles triangles, in ΔAPB, ∠PAB and ∠PBA are equivalent. Let the measure of each of them be x°.

Likewise, in ΔCPB, ∠PCB and ∠PBC are equivalent.

And since AP = BP = PC, each of the angles∠PCB and ∠PBC will also be equivalent to x°.

And since the sum of the interior angles of a triangle total 180°, we acquire:

[tex]\angle PAB+\angle PBA+\angle PCB+\angle PBC=180[/tex]

Since they are all equivalent:

[tex]4x=180[/tex]

Hence:

[tex]x=45^\circ[/tex]

∠ABC is the sum of ∠PBA and ∠PBC, each of which measures 45°. Hence:

[tex]\angle ABC=\angle PBA+\angle PBC=45+45=90^\circ[/tex]

this is your answer look it once.
