i think
21 = 4x - 9 - x
what is x?
Answer:
x = 10
Step-by-step explanation:
21 = 4x - 9 - x
21 = 3x - 9
30 = 3x
10 = x
Answer:
x = 10
Step-by-step explanation:
Given
21 = 4x - 9 - x, that is
21 = 3x - 9 ( add 9 to both sides )
30 = 3x ( divide both sides by 3 )
10 = x

The number line that represents opposite numbers is (a) number line 1
How to determine the number line?From the question, we understand that:
The numbers are opposite numbers
Take for instance, we have a number x.
The opposite of the number x is -x
So, the number line that represents opposite numbers must have points at x and -x
Let x = 10.
So, we have:
Opposite numbers = 10 and -10
So, the number line that represents opposite numbers must have points at 10 and -10
Hence, the number line that represents opposite numbers is (a) number line 1

What is the probability that the same result (heads or tails) shows twice in a row exactly once in the ten tosses?
Answer:
1/512
Step-by-step explanation:
The probability is 2 out of 2^10 , because there are only two sequences when same result (heads or tails) shows twice in a row exactly once in the ten tosses (HTHTHTHTHT and THTHTHTHTH) out of 2^10 possible sequences.
2/2^10 = 2/1024 =1/512
To be labeled as a jumbo egg, the egg is supposed to weigh 2.5 oz. Mia buys a carton of jumbo eggs and measures one of the eggs as 2.4 oz. What is the percent error? *
Answer: 4.17%
Step-by-step explanation:
Formula for percentage error = [tex]\dfrac{|\text{Estimated weight - Actual weight}|}{\text{Actual weight}}\times100[/tex]
Given: Estimated weight = 2.5 oz
Actual weight = 2.4 oz
Percentage error = [tex]\dfrac{2.5-2.4}{2.4}\times100\%[/tex]
[tex]=\dfrac{0.1}{2.4}\times100\%\\\\=\dfrac{100}{24}\%=4.17\%[/tex]
Hence, the percent error = 4.17%
The function c(x) = 18x -10 represents the cost in dollars. How many tickets can you buy?
Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.
So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 170 dollars.
The solution would still clear your concept though.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]c(x) = 18x -10[/tex]
The slope-intercept form of the line equation
We know that the slope-intercept form of the line equation
y=mx+b
where m is the slope and b is the y-intercept
so
[tex]c(x) = 18x - 10[/tex]
comparing with the slope-intercept form of the line equation
here:
rate of change = 18c(x) or y represents the costand
'x' represents the number of tickets
Assuming the total cost i.e. c(x) = $170
In order to determine the value of x, set c(x) = 170
i.e.
170 = 18x -10
switch sides
18x - 10 = 170
add 10 to both sides
18x - 10 + 10 = 170 + 10
18x = 180
Divide 18 to both sides
18x/18 = 180/18
x = 10
Therefore, if you can buy x = 10 tickets if you pay 170 dollars.

Describe the lines below as parallel, perpendicular,or neither.
3x+6y=42 and y=2x-1
Answer:
They are neither perpendicular nor parallel.
Step-by-step explanation:
Find the gradient of 2x + 6y = 42 by rearranging it in the form y = mx + c:
6y = -2x + 42
y = -(1/3)x + 7
The gradient is the co-efficient of x
Therefore the gradient is -(1/3)
The gradient of y = 2x - 1 is 2.
If they were parallel they would have the same gradient.
If they were perpendicular then the gradient of one would be the negative reciprocal of the other, e.g: if one was 2, the other would be -(1/2).
Neither of these are true, so they are neither perpendicular nor parallel.
The lines 3x+6y=42 and y=2x-1 are perpendicular
Two lines are parallel if they have equal slope
Two lines are perpendicular if the product of their slopes equals -1
The given lines are:
3x+6y=42 and y=2x-1
Rewrite each of the equations in the form y = mx + c
For line 3x + 6y = 42:
[tex]6y = -3x + 42\\\\y=\frac{-3}{6} x+\frac{42}{6}\\\\y=-0.5x+7[/tex]
The slope, m₁ = -0.5
For line y = 2x - 1
The slope, m₂ = 2
Since m₁ ≠ m₂, lines 3x+6y=42 and y=2x-1 are not parallel
m₁ m₂ = -0.5(2)
m₁ m₂ = -1
Since the product of the slopes equals -1, the lines 3x+6y=42 and y=2x-1 are perpendicular

Emiliana pays 6% sales tax on a cupcake that costs 3 dollars. How much does the sales tax add to the purchase price? Please tell me how you got the answer. (answer choices: $0.018, $18, $0.18, $3.18)
Answer:
$0.18 sales tax will be added to the purchase price.
Step-by-step explanation:
Given that:
Cost of cupcake = $3
Sales tax applied = 6%
Amount of sales tax = 6% of cost of cupcake
Amount of sales tax = [tex]\frac{6}{100}*3[/tex]
Amount of sales tax = 0.06 * 3 = $0.18
Hence,
$0.18 sales tax will be added to the purchase price.

A salesman gets a basic wage of £160 per week plus a commision of 30%
of the sales he makes that week.
In one week his total wage was £640
Work out the value of the sales he made that week.
Answer:
The value of the sales that week was £1,600
Step-by-step explanation:
The wage of a salesman is made of two parts: A fixed-wage of £160 per week plus a commission of 30% (0.3) of the sales he makes that week.
The wage can be modeled by the function:
W = 160 + 0.3x
Where x is the amount of sales per week.
If he had a total wage of £640, then we can find the values of the sales by solving for x the equation
160 + 0.3x = 640
Subtracting 160:
0.3x = 640 - 160
0.3x = 480
Dividing by 0.3:
x = 480/0.3
x = 1,600
The value of the sales that week was £1,600
