How do you solve 6-9(4p-3)= 2(6p+7)+3

Alika [10]

Answer:

p= 1/3

=0.333

Step-by-step explanation:

Simplifying

6 + -9(4p + -3) = 2(6p + 7) + 3

Reorder the terms:

6 + -9(-3 + 4p) = 2(6p + 7) + 3

6 + (-3 * -9 + 4p * -9) = 2(6p + 7) + 3

6 + (27 + -36p) = 2(6p + 7) + 3

Combine like terms: 6 + 27 = 33

33 + -36p = 2(6p + 7) + 3

Reorder the terms:

33 + -36p = 2(7 + 6p) + 3

33 + -36p = (7 * 2 + 6p * 2) + 3

33 + -36p = (14 + 12p) + 3

Reorder the terms:

33 + -36p = 14 + 3 + 12p

Combine like terms: 14 + 3 = 17

33 + -36p = 17 + 12p

Solving

33 + -36p = 17 + 12p

Solving for variable 'p'.

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

Add '-12p' to each side of the equation.

33 + -36p + -12p = 17 + 12p + -12p

Combine like terms: -36p + -12p = -48p

33 + -48p = 17 + 12p + -12p

Combine like terms: 12p + -12p = 0

33 + -48p = 17 + 0

33 + -48p = 17

Add '-33' to each side of the equation.

33 + -33 + -48p = 17 + -33

Combine like terms: 33 + -33 = 0

0 + -48p = 17 + -33

-48p = 17 + -33

Combine like terms: 17 + -33 = -16

-48p = -16

Divide each side by '-48'.

p = 0.3333333333

Simplifying

p = 0.3333333333

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other. Find the length of the other piece

sergeinik [125]

Answer:

The length of the other piece is 38 inch.

Step-by-step explanation:

Given:

A 190 inch pipe is cut into 2 pieces. One piece is 4 times the length of the other.

Now, to find the length of the other piece.

Let the length of the other piece be $x$ .

And the length of one piece be $4x$ .

The total length of the pipe = $190 inch$

According to question:

$4x+x=190$

⇒ $5x=190$

<em>Dividing both sides by 5 we get:</em>

⇒ $x=38$

Therefore, the length of the other piece is 38 inch.

A cone has a mass of 6g and a radius of 5cm and a height of 2cm what is the density

goblinko [34]

Step $1$

we know that

The density's formula is equal to

$density=\frac{mass}{volume}$

The volume of a cone is equal to

$Volume=\frac{1}{3}\pi r^{2} h$

where

r is the radius of the base of the cone

h is the height of the cone

in this problem

$r=5cm\\ h=2 cm$

substitute the values in the formula above

$Volume=\frac{1}{3}*\pi*5^{2}*2$

$Volume=52.36\ cm^{3}$

Step $2$

Find the density

we have

$Volume=52.36\ cm^{3}$

$mass=6\ g$

substitute in the formula

$density=\frac{mass}{volume}$

$density=\frac{6}{52.36}$

$density=0.11\frac{g}{cm^{3} }$

therefore

<u>the answer is</u>

the density is $0.11\frac{g}{cm^{3} }$

4. Find the volume of the figure. The base is a square.

GREYUIT [131]

Answer:

A) 283500 ft³

B) 1057.26 π in³

Step-by-step explanation:

A) Volume of square based pyramid

= 1/3 × Area of the base × height

= 1/3 × (90 ft)² × 105 ft

= 283500 ft³

B) This figure is a composite figure

Step 1

Find the volume of the cone

=1/3 πr²h

r = radius = 8.5 in

h = height = 10 in

= 1/3 × π × (8.5 in)² × 10 in

= 240.83333333 π in³

≈ 240.83 π in³

Step 2

Find the volume of the cylinder

= πr²h

= r = radius = 8.5 in

h = height = 11.3 in

= π × (8.5 in)² × 11.3 in

= 816.425 π in³

≈ 816.43π in³

Volume of the figure = (240.83 π + 816.43 π) in³

= 1057.26 π in³
