Identify the property of equality that justifies the missing step in solving the equation below
Answer:
property of equality that justifies the missing step is Division property of equality
Step-by-step explanation:
We need to Identify the property of equality that justifies the missing step
[tex]28=4x-8\\28+8=4x\\36=4x[/tex]
Now, we divide both sides by 4 using division property of equality as it states that [tex]\frac{a}{c}=\frac{b}{c}[/tex]
[tex]\frac{36}{4}=\frac{4x}{4}\\9=x[/tex]
So, The property of equality that justifies the missing step is Division property of equality
Nicole bought six pounds of apples at $1.50 per pound. The store had a discount of $2 off her total purchase. Nicole and her friend then divided the cost of the purchase evenly. Which expression can be used to determine how much Nicole and her friend each paid for the apples?
A)[(6 × 1.50) – 2] ÷ 2
B) 6 × 1.50 – 2 ÷ 2
C) 6 × [1.50 – (2 ÷ 2)]
D) 6 × 1.50 – (2 ÷ 2)
Answer:
Answer: (A) [(6 x 1.5) - 2] ÷ 2
Step-by-step explanation:
Find the cost of 6 pounds of apples:
1 pound = $1.50
6 pounds = 6 x 1.5
Price after discount:
Discount = $2
Price after discount = (6 x 1.5) - 2
The cost is shared with her friend:
One person = [(6 x 1.5) - 2] ÷ 2
Answer: (A) [(6 x 1.5) - 2] ÷ 2

Read the excerpt from The Crisis, Number I by Thomas Paine.
“I once felt all that kind of anger, which a man ought to feel, against the mean principles that are held by the Tories: a noted one, who kept a tavern at Amboy, was standing at his door, with as pretty a child in his hand, about eight or nine years old, as I ever saw, and after speaking his mind as freely as he thought was prudent, finished with this unfatherly expression, ‘Well! give me peace in my day.’ Not a man lives on the continent but fully believes that a separation must some time or other finally take place, and a generous parent should have said, ‘If there must be trouble, let it be in my day, that my child may have peace;’ and this single reflection, well applied, is sufficient to awaken every man to duty.”
Which is a central idea of this excerpt?
Paine feels that everyone should be able to speak freely, which is why he supports independence.
Paine believes that colonists should fight for independence so their children can live in peace.
Paine believes that some people are selfish and place their needs above others.
Paine felt anger for the first time when he saw an interaction between a Tory and a child.

16-+4y+5x=0
-48-12y=-9x
The system of equations 16 + 4 y + 5 x = 0 and - 48 - 12 y = - 9 x will have the solution as x = 0 and y = - 4.
We are given a system of equations as:
16 + 4 y + 5 x = 0 … (1)
- 48 - 12 y = - 9 x
- 16 - 4 y = - 9 x
9 x - 16 = 4 y … (2)
Substitute the equation (2) in the equation (1), we get that:
16 + 9 x - 16 + 5 x = 0
14 x = 0
x = 0
4 y = 9 ( 0 ) - 16
4 y = - 16
y = - 16 / 4
y = - 4
Therefore, we get that, the system of equations 16 + 4 y + 5 x = 0 and - 48 - 12 y = - 9 x will have the solution as x = 0 and y = - 4.

I need help with this equation can you help me understand this?
Answer:−589.86
Step-by-step explanation:
let unknown number be x
Solve for x
655.4+x=65.54
Subtract 655.4 from both sides.
x=65.54−655.4
Subtract 655.4 from 65.54 to get −589.86.

The balance owed on your credit card triples from $800 to $2400 in 9 months. If the balance is growing linearly then it would take 34.9 months to reach $7000. If, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months? Round your answer to the nearest cent.
If, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months is: $56,954.45.
ExponentialUsing the given exponential to determine what would the balance be after 34.9 months.
f(x)=800(1+0.13)x
Where:
x=number of months
Hence:
f(x)=800(1+0.13)x
f(x)=800(1+0.13)^34.9
f(x)=800(1.13)^34.9
f(x)=800(71.19306287)
f(x)= $56,954.45
Therefore if, on the other hand, the balance is growing exponentially, f(x)=800(1+0.13)x where x represents the number of months, what would the balance be after 34.9 months is: $56,954.45.

x + 2x -75 = 90
3x = 90+75
3x = 165
x = 55
Measure of A = 55
Measure of B = 2(55) - 75 = 110 - 75 = 35
28.
2x+10-x+55 = 90
x = 90-65
x = 25
measure of A = 2(25) +10 = 60
measure of B = -25+55 = 30
31.
2x+3+3x - 223 = 180
5x -220 = 180
5x = 400
x = 80
measure of A = 163
measure of B = 17

-4x+40+x+50 = 180

Can someone explain these two?
Answer:
I believe you cancel out values if there are the same ones for the numerator and dominator.
For example:
[tex]\frac{x^4+x^2+x-3}{x^4+x^3-3}[/tex]
Since both the numerator and dominator have [tex]x^4[/tex] and -3, you are able to cancel them out.
This would leave you with [tex]\frac{x^2+x}{x^3}[/tex]
Notes: the exponents have to be the same number in order to cancel out the values.
Answer:
11. C) x +1
12. B) x -1
Step-by-step explanation:
You want the simplified form of a couple given rational expressions.
Each of the polynomials can be factored by pairs. Common factors can be cancelled.
11.Factoring numerator and denominator pairwise, we have ...
[tex]\dfrac{x^3+2x^2-x-2}{x^2+2x-x-2}=\dfrac{x^2(x+2)-1(x+2)}{x(x+2)-1(x+2)}=\dfrac{(x^2-1)(x+2)}{(x-1)(x+2)}\\\\=\dfrac{x^2-1}{x-1}=\dfrac{(x+1)(x-1)}{(x-1)}=\boxed{x+1}[/tex]
12.Factoring the numerator pairwise,, we have ...
[tex]\dfrac{x^5-x^4+x^3-x^2+x-1}{x^4+x^2+1}=\dfrac{x^4(x-1)+x^2(x-1)+1(x-1)}{x^4+x^2+1}\\\\=\dfrac{(x^4+x^2+1)(x-1)}{(x^4+x^2+1)}=\boxed{x-1}[/tex]

solve linear equation
[tex] \Large{\boxed{\sf x = 4}} [/tex]
[tex] \\ [/tex]
Explanation:Solving this equation means finding the value of 'x' that makes the equality true.
[tex] \\ [/tex]
Given equation:
[tex] \sf -12 + 5x - x = x - 7 + 7 [/tex]
[tex] \\ [/tex]
Combine like terms:
[tex] \sf -12 + (5x - x) = x + (-7 + 7) \\ \\ \sf -12 + 4x = x [/tex]
[tex] \\ [/tex]
Now, we move the variables to the right side of the equation by subtracting 4x from both sides:
[tex] \sf -12 + 4x - 4x = x - 4x \\ \\ \sf -12 = -3x [/tex]
[tex] \\ [/tex]
Finally, divide both sides of the equation by the coefficient of the variable, -3:
[tex] \sf \dfrac{-12}{-3} = \dfrac{-3x}{-3} \\ \\ \\ \boxed{\boxed{\sf x = 4}} [/tex]

what is the value of x?
help would be so appreciated!
Answer:
x =23
Step-by-step explanation:
ok first, the full degree of a straight line is 180°
subtract 38° out of 180°
180-38= 142
so 6x+4= 142°
subtract 4 from both sides of the equation
6x +4 -4= 142-4
6x=138
divide 6 from 6x and 138
x=23
