Answer:
x=0
Step-by-step explanation:
7x+(-7)=9x-7
Add 7 to each side
7x+(-7)7=9x-7+7
7x = 9x
Subtract 7x from each side
7x-7x = 9x-7x
0 = 2x
Divide by 2
0 = 2x/2
0 = x
Hello,
I hope you and your family are staying safe and healthy!
Answer: 0
Step-by-step explanation:
[tex]7x + (-7) = 9x - 7[/tex]
[tex]7x - 7 = 9x - 7[/tex]
Now susbtract [tex]9x[/tex] from both sides
[tex]7x -7 - 9x = 9x - 7 - 9x\\-2x - 7 = -7[/tex]
Then add 7 to both sides
[tex]-2x - 7+7=-7+7\\2x=0[/tex]
[tex]x = \frac{0}{-2} \\x = 0[/tex]

Answer:
x=0.0000−3.0000i
x=0.0000+3.0000i
Hoped I helped
Answer:
x = 3√3 - 3
x = -3√3 - 3
Step-by-step explanation:
(3+x)² + 9 = 36
(x + 3)² + 9 - 9 = 36 - 9
(x + 3)² = 27
x + 3 = 3√3
x + 3 = -3√3
therefore,
x = 3√3 - 3
x = -3√3 - 3

Mr. Doss reached into a bag and pulled out a handful of counters. He pulled out 16 negative counters and 27 positive counters. What was the combined value of the counters?
Answer: 11
Step-by-step explanation:
Given: Mr. Doss pulled out 16 negative counters and 27 positive counters.
In integers we use negative sign "-" to represent the negative quantities.
So, we can represent 16 negative counters as -16.
Now, combined value of the counters = (-16) + 27
= 27-16
= 11
Hence, the combined value of the counters is 11.

what is the value of x. 1.6(15x + 25)= -6x -5
Answer:
[tex]x = - \frac{3}{2} \: \: \: or \: \: - 1.5[/tex]Step-by-step explanation:
1.6(15x + 25)= -6x -5
Multiply the terms
That's
24x + 40 = - 6x - 5
Add 6x to both sides
24x + 6x + 40 = 6x - 6x - 5
30x + 40 = - 5
Subtract 40 from both sides
That's
30x + 40 - 40 = - 5 - 40
30x = - 45
Divide both sides by 30
We have the final answer as

Eight car dealerships reported the number of cars they sold last month. Car Dealership Number of Cars Sold GMC 84 Chevrolet 81 Nissan 92 Toyota 92 Ford 95 Honda 94 Hyundai 80 Acura 72 What is the interquartile range of this set of data? 5 7.5 12.5 23
Answer:
10.75Step-by-step explanation:
Interquartile R range of an ungrouped data is expressed as R = Q3-Q1 where;
Q3 is the third quartile
Q1 is the first quartile
Given the Car Dealership Number of Cars Sold GMC as 84 Chevrolet 81 Nissan 92 Toyota 92 Ford 95 Honda 94 Hyundai 80 Acura 72
First let us arrange them in ascending order;
72, 80, 81, 84, 92, 92, 94, 95
Q3 = 3(n+1)/4 th observation where n is the total number of cars
Q3 = 3(8+1)/4 = 27/4
Q3 = 6.75th observation
Q3 = 6th obsrvation - 0.75(7th observation - 6th observation)
Q3 = 92-0.75(94-92)
Q3 = 92-0.75(2)
Q3 = 90.5
The 6.75th observation of the data is 90.5
Q1 = (n+1)/4 th observation where n is the total number of cars
Q1 = (8+1)/4 = 9/4
Q1 = 2.25th observation
Q1 = 2nd observation - 0.25(3rd observation - 2nd observation)
Q1 = 80-0.25(81-80)
Q1 = 80-0.25(1)
Q1 = 79.75
Interquartile range = Q3 - Q1
Interquartile range = 90.5 - 79.75
Interquartile range = 10.75
Answer:
the answer is 12.5

Simplify the expression and rationalize the demonimator when appropriate, please show steps : >
Answer:
[tex]=-3tv^2[/tex]
Step-by-step explanation:
So we have the expression:
[tex]\sqrt[3]{3t^4v^2}\sqrt[3]{-9t^{-1}v^4}[/tex]
To simplify, combine the two radicals. Since they have the same index, we can combine them. Thus:
[tex]=\sqrt[3]{(3t^4v^2)(-9t^{-1}v^4)}[/tex]
Combine like terms:
[tex]=\sqrt[3]{(3\cdot -9)(t^4\cdot t^{-1})(v^2\cdot v^4)}[/tex]
Multiply. When multiplying the exponents, simply add the exponents:
[tex]=\sqrt[3]{-27t^3v^6}[/tex]
Now, simplify. Note that -27 can be written as (-3)^3. t^3 can be written as (t)^3 and v^6 can be written as (v^2)^3. Thus:
[tex]=\sqrt[3]{(-3)^3(t)^3(z^2)^3}[/tex]
Combine them all under one exponent:
[tex]=\sqrt[3]{(-3tv^2)^3}[/tex]
Cancel out the cube root:
[tex]=-3tv^2[/tex]
And this is the simplest it can get.
And we are done :)
Edit: Typo
Answer:
-3v²t
Step-by-step explanation:
[tex]\sqrt[3]{3t^4v^2} \sqrt[3]{-9t^-1v^4}[/tex]
= [tex]\sqrt[3]{3t} \sqrt[3]{v^2t} \sqrt[3]{-9v^4t^-1}[/tex]
= [tex]\sqrt[3]{3t} (-\sqrt[3]{9v^4/t)} \sqrt[3]{v^2t}[/tex]
= - [tex]\sqrt[3]{3t} \sqrt[3]{v^2 9v^4/t}t[/tex]
= - [tex]\sqrt[3]{3} \sqrt[3]{9t} \sqrt[3]{v^6}[/tex]
= - [tex]\sqrt[3]{3*9}v^2t[/tex]

Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm, what is her total pay for the week?
Answer:
$328.13
Step-by-step explanation:
First, find the amount of time she works every day.
Between 8:45 and 5:15, there are 8.5 hours.
Subtract 1 for her lunch break, so there are 7.5 hours worked every day
Then, calculate how much she gets every day:
7.5(8.75)
= $65.625
Multiply this by 5 to find her pay for the week:
65.625(5)
= $328.13 is her total pay for the week
The total pay for the week will be $318.75.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Amanda Roberts works a Monday through Friday work week at a rate of $8.75 per hour. She takes a 1- hour lunch break. If she clocks in each day at 8:45 am and leaves at 5:15 pm.
The number of hours from 8:45 am to 5:15 pm will be 8.5 hours.
And the number of working days will be 5.
Then the total pay for the week will be

Find the domain and range of the function represented by the graph. A Domain: −3
Answer:
Domain: (-3, 1]
Range: [-4, 0)
Step-by-step explanation:
Domain is all the x-values that can be plugged into the graph.
Range is all y-values that are outputted from inputting x.
We can see that our x-values span from -3 to 1. Since -3 is open dot, it is not included. Brackets signify inclusion.
(-3, 1]
We can see that our y-values span from -4 to 0. Since when x = -3 is open dot, the output y = 0 is also not included.

What are the first five multiples of 12?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
A multiple is a number that can be divided by that number with no remainder. For example, multiples of 5 are 5, 10, 15, and 20.
A multiple of 12 is basically 12 × (number of multiple), for example, if you want the second multiple of 12, you would multiply 2 by 12.
So multiply 12 by 1, 2, 3, 4, and 5.
12×1=12
12×2=24
12×3=36
12×4=48
12×5=60
The first five multiples of 12 are 12, 24, 36, 48, and 60.
