Answer:
9
Step-by-step explanation:
its difficult to explain but I found that there is a 10.3%Tax so 10.3% of 93 is 9
The sales tax on the second item, which cost $93 before tax, would be approximately $8.99 based on the tax rate of the first item.
Explanation:To determine the amount of sales tax on the second item, we first need to understand the rate of sales tax applied to the first item. The sales tax on the first item was $21 on a pre-tax cost of $217. So, the tax rate would be 21 divided by 217, which is approximately 0.0967, or 9.67%.
If we apply this tax rate to the second item, which costs $93 before tax, we get 93 times 0.0967, or $8.99. Therefore, the amount of sales tax on the second item would be approximately $8.99.

What is 14/18 as decimal
Answer:
14/18 = 0.778
Step-by-step explanation:
14 divided by 2 = 7
18 divided by 2 = 9
7/9 is the same as 7 divided by 9
= 0.778
The decimal equivalent of [tex]\( \frac{14}{18} \)[/tex] is approximately 0.777777777777778.
To convert [tex]\( \frac{14}{18} \)[/tex] to a decimal, one divides 14 by 18. This can be done by hand or with a calculator. When dividing 14 by 18, the result is a repeating decimal where the digit 7 repeats indefinitely. This repeating decimal can be represented as 0.777777777777778 when rounded to the nearest 10th decimal place.
Alternatively, one can simplify the fraction [tex]\( \frac{14}{18} \)[/tex] before converting it to a decimal. By dividing both the numerator and the denominator by their greatest common divisor, which is 2, the fraction simplifies to [tex]\( \frac{7}{9} \)[/tex]. When 7 is divided by 9, the result is again the repeating decimal 0.777777777777778.
In summary, [tex]\( \frac{14}{18} \)[/tex] simplifies to [tex]\( \frac{7}{9} \)[/tex] and as a decimal, it is approximately 0.777777777777778.

Allen Barry deposited checks
totaling $1,584.19 into his savings
account. He withdrew $96.00 while
depositing some loose change. Allen's
total deposit was $1,530.24. How much
did he deposit in loose change?
Answer:
$42.05
Step-by-step explanation:
Take $96.00 from 1,584.19 to figure out how much he had before he deposited
1,584.19 - 96 = 1,488.19
Now take away what he had after he took 96, to after he added.
1,530.24 - 1,488.19 = 42.05

|2x-4|=22
Answer:
2x-4 = 22
2x = 26
x=13 check |26-4|=22
-(2x-4) = 22
-2x+4 = 22
-2x = 18
x=-9 Check |-18 -4| = |-22| = 22
Answer:
x=13
Step-by-step explanation:
Finding the answer to this is very simple actually. you can actually solve this problem without the || because x has to be a positive value for this to work. 2x-4=22 can be done by adding 4 to both sides and getting the answer 26. Isolate the variable by dividing both sides by 2 to get x=13
2x - 3y = 3
x + 2y = 5
by substitution or elimination
2x - 3y = 3
x + 2y = 5
In the second equation we have an x-term that has a coefficient of 1 (which means the x is all by itself), so we can isolate that x and solve by substitution.
x + 2y = 5
x + 2y - 2y = 5 - 2y
x = 5 - 2y
The expression 5 - 2y will be substituted for x in the first equation.
2x - 3y = 3
2(5 - 2y) - 3y = 3
Solve for y.
2(5 - 2y) - 3y = 3
10 - 4y - 3y = 3 (distribute the 2)
10 - 7y = 3 (collect like terms)
-7y = -7 (subtract 10 from both sides)
y = 1 (divide both sides by -7)
Substitute 1 for y in the second equation to find x.
x + 2y = 5
x + 2(1) = 5
Solve for x.
x + 2(1) = 5
x + 2 = 5 (multiply)
x = 3 (subtract 2 from both sides)
Always check your work. Substitute into the original system.
2x - 3y = 3
2(3) - 3(1) = 3
6 - 3 = 3
3 = 3
x + 2y = 5
3 + 2(1) = 5
3 + 2 = 5
5 = 5

A line is parallel to y = 3x - 12 and
intersects the point (1, -2). What is the
equation of this parallel line?
Answer:
y=3x-5
Step-by-step explanation:
parallel means that both lines share the same gradient.
from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form
now substitute values into formula
y-y1=m (x-x1)
y--2=3 (x-1)
expand brackets and simplify
y+2=3x-3
subtract 2 from both sides of equation
y=3x-5
let f be a linear function such that f(1)=5 and f(3)=9. Find an equation for f(x)

What is the equation for the line that passes through the points (-5, 2) and (5,-6)?
Answer:
4x + 5y = -10 or y = -⅘x - 2
Step-by-step explanation:
First, find the rate of change [slope]:
-y₁ + y₂\-x₁ + x₂ = m
[tex] \frac{ -2 - 6}{5 + 5} = - \frac{8}{10} = - \frac{4}{5} [/tex]
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y + 6 = -⅘(x - 5)
y + 6 = -⅘x + 4
- 6 - 6
_______________
y = -⅘x - 2
If you want it in Standard Form:
y = -⅘x - 2
+⅘x +⅘x
___________
⅘x + y = -2 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅘x + y = -2]
4x + 5y = -10 >> Line in Standard Form
__________________________________________________________
y - 2 = -⅘(x + 5)
y - 2 = -⅘x - 4
+ 2 + 2
______________
y = -⅘x - 2
y = -⅘x - 2
+⅘x +⅘x
___________
⅘x + y = -2 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅘x + y = -2]
4x + 5y = -10 >> Line in Standard Form

Liam bought a comic book and had $5 left. If he had a total of $8 walking into the store, how much did he spend on the comic book?
Liam used the equation 5x=8 to model the problem. He said that x represents the amount of money he spent. Liam said that the solution, x=1.6, means that he spent $1.60. Is he correct? Why or why not? If he is incorrect find the correct answer showing your work.
Pls Help Me
Answer: The comic book was $3.
Step-by-step explanation:
Instead of 5x=8, it should have been 5+x=8 because he only purchased a single comic book. Subtract 5 from 8 and your X value is 3.
Answer:
Liam spent $3 on the book.
Step-by-step explanation:
Liam bought a comic book and had $5 left.
He had a total of $8 walking into the store, so he spent [tex]8-5=3[/tex] dollars on the comic book.
Liam used the equation 5x=8 to model the problem.
This is wrong. The correct form would have been [tex]8-x=5[/tex] or [tex]5+x=8[/tex] where x represents the amount of money he spent.
Hence, Liam spent $3 on the book.
Malachi’s garden is 2 3/5 meters long. He wants to plant tomato plants every 1/5 of a meter. How many plants can Malachi fit?
Answer:
13 plants.
Step-by-step explanation:
We have been given that Malachi’s garden is 2 3/5 meters long. He wants to plant tomato plants every 1/5 of a meter.
To find the number of tomato plant that will fit the garden, we will divide length of garden by 1/5 as:
[tex]\text{Number of tomato plant that will fit the garden}=2\frac{3}{5}\div \frac{1}{5}[/tex]
Convert mixed fraction into improper fraction:
[tex]2\frac{3}{5}\Rightarrow\frac{2\times5+3}{5}=\frac{10+3}{5}=\frac{13}{5}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\div \frac{1}{5}[/tex]
Convert to multiplication problem by flipping the 2nd fraction:
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\times \frac{5}{1}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{1}\times \frac{1}{1}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=13[/tex]
Therefore, 13 plants will fit Malachi's garden.

Let n = the number
(1/5)n - 7
12x +10+3+8x ? What do I have to do ?
Simplifying
12x + 10 + 3 + 8x = 0
Reorder the terms:
10 + 3 + 12x + 8x = 0
Combine like terms: 10 + 3 = 13
13 + 12x + 8x = 0
Combine like terms: 12x + 8x = 20x
13 + 20x = 0
Solving
13 + 20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 20x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 20x = 0 + -13
20x = 0 + -13
Combine like terms: 0 + -13 = -13
20x = -13
Divide each side by '20'.
x = -0.65
Simplifying
x = -0.65
Answer:
You have to do like terms
Step-by-step explanation:
12x+10+8+8x
12x+8x = 20x
10+3 = 13
your answer would be
20x+10
A lawyer has an annual income of $173, 482 and will pay a 5.5% income tax rate. What is the amount of income tax in dollars and cents that the lawyer will have too pay?
Final answer:
The lawyer with an annual income of $173,482 and a tax rate of 5.5% will pay $9,541.51 in income taxes.
Explanation:
To calculate the amount of income tax that the lawyer needs to pay, we multiply their annual income by the income tax rate. In this case, the lawyer has an annual income of $173,482 and the income tax rate is 5.5%. The calculation would be:
Income Tax = Annual Income × Income Tax Rate
Income Tax = $173,482 × 0.055
Income Tax = $9,541.51
Therefore, the lawyer will pay $9,541.51 in income taxes.
