expand the following by using the distributive property: 6(-3w+1/3)

Answers

Answer:

-18w+2

Step-by-step explanation:

6*-3w=-18w

1/3*6=2

The resultant expression is -18w + 2 which could represent the expanded form by using the distributive property.

What is the expression?

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question as follows:

6(-3w+1/3)

We have to expand the given expression by using the distributive property.

As per the question, we have

⇒ 6(-3w+1/3)

Apply the distributive property of multiplication,

⇒ 6 × (-3w)+ 6 × (1/3)

⇒ -18w + 6/3

⇒ -18w + 2

Therefore, the resultant expression is -18w + 2.

q=-2 when p=1

Step-by-step explanation:

Answer:

q = -2

Step-by-step explanation:

7p + 5q = -3

=> 7x1 + 5q = -3

=> 7 + 5q = -3

7(p + 3) + 9 = 5(p – 2) – 3p What is P

Answers

Answer:

p = -8

Step-by-step explanation:

Step 1: Write equation

7(p + 3) + 9 = 5(p - 2) - 3p

Step 2: Solve for p

Distribute: 7p + 21 + 9 = 5p - 10 - 3pCombine like terms: 7p + 30 = 2p - 10Subtract 2p on both sides: 5p + 30 = -10Subtract 30 on both sides: 5p = -40Divide both sides by 5: p = -8

Step 3: Check

Plug in x to verify it's a solution.

Substitute: 7(-8 + 3) + 9 = 5(-8 - 2) - 3(-8)Parenthesis: 7(-5) + 9 = 5(-10) + 24Multiply: -35 + 9 = -50 + 24Add: -26 = -26

Which expressions are equivalent to -6n+(-12)+4

A 4(n - 3) - 6n

B 2(2n - 6)

C None of the above

Answers

Well first try expanding a and b...
for example, you want to start by multiplying 4•n and 4•-3... what do you get? Well 4•n= 4n and 4•-3= -12. So A is 4n+(-12)-6n and then you want to further minimize this, so you would combine 4n and -6n. 4n+(-6n)= -2n. Therefore A= -2n+(-12). This is not the original equation. Do the same for B to finish solving.

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:



At what number(s) measures played would the sound level be at 80 decibels?

Answers

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

[tex]s = 10|x - 4| + 50[/tex]

Required

Solve for x when s = 80

Substitute 80 for x

[tex]80 = 10|x - 4| + 50[/tex]

Subtract 50 from both sides

[tex]80 - 50= 10|x - 4| + 50 - 50[/tex]

[tex]30= 10|x - 4|[/tex]

Divide through by 10

[tex]\frac{30}{10}= \frac{10|x - 4| }{10}[/tex]

[tex]3= |x - 4|[/tex]

Reorder

[tex]|x - 4| = 3[/tex]

This can be split into

[tex]x - 4 = 3[/tex] or [tex]x - 4 = -3[/tex]

Solve for x

[tex]x = 4 + 3[/tex] or [tex]x = 4 - 3[/tex]

[tex]x = 7[/tex] or [tex]x = 1[/tex]

Hence:

The numbers of measure of music played are 1 and 7

Satellites in low-Earth orbit circle around our planet at about 4.72 miles per second. A satellite that relayed a phone text message traveled 16.52 miles before the message reached the recipient. How long did it take the text to go from phone to phone? It took the text seconds to go from phone to phone.

Answers

Answer: 3.5

Step-by-step explanation:

Divide 16.52 by 4.72. It equals 3.5.

Using the speed - distance relationship, the time it'll take for the text to travel from phone to phone is 3.5 seconds.

Given the parameters :

Transmission speed = 4.72 miles per second

Distance traveled = 16.52 miles

Recall :

Time = Distance ÷ Speed

Time taken = (16.52 / 4.72) = 3.5 seconds.

The time it took the text to travel from phone to phone is 3.50 seconds.

Step-by-step explanation:

-6x + 10 = -104

-6x = -114

x = 19

Answer:

[tex]\boxed {x = 19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

-[tex]6x + 10 = -104[/tex]

-Subtract [tex]10[/tex] to both sides:

-[tex]6x + 10 - 10 = -104 -10[/tex]

-[tex]6x = -114[/tex]

-Divide both sides by [tex]6[/tex]:

[tex]\frac{-6x}{-6} = \frac{-114}{-6}[/tex]

[tex]\boxed {x = 19}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]19[/tex].
