If 7p + 5q = -3, find q when p = 1.
Answers
Answer:
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
=> 5q = -3 - 7 = -10
=> q = -2
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
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 = -8Step 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 = -26Please help meeeee !!!

-6x +10 = -104
what’s x ?
Answers
Answer:
19
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].

Which expressions are equivalent to -6n+(-12)+4
A 4(n - 3) - 6n
B 2(2n - 6)
C None of the above
Answers
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.

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.
