Christian can calculate his total earnings over 2 weeks by simplifying the expression x + 10 + x + 10 to 2(x + 10). This method combines his earnings from fixing bicycles and his allowance for each week. Therefore, the correct answer is D. 2(x + 10).
To calculate how much Christian will earn in total over 2 weeks, you can simplify the expression x + 10 + x + 10:
First, combine like terms for the amount he earns from fixing bicycles: x + x = 2x.Next, combine the constants for his allowance: 10 + 10 = 20.This gives us the total expression: 2x + 20.Rewriting this, you get 2(x + 10). Therefore, the correct answer is D. 2(x + 10).

can someone help me out
I don't see in the problem what she is paid for over time but it is normally 1.5 times per hour
so 40 hours at 25 = 1000
51-40 = 11 hours of over time
25 *1.5 = 37.50 per hour for over time
11 * 37.50 = 412.50
1000+412.50 = 1412.50 total

17 − 2v = 41 solve v
Final answer:
To solve the equation 17 - 2v = 41, subtract 17 from both sides to get -2v = 24. Then divide both sides by -2 which gives v = -12.
Explanation:
To solve the equation 17 - 2v = 41 for v, first we need to isolate v on one side of the equation. We can start by subtracting 17 from both sides to rid the left side of numbers without the variable v. This gives us the equation:
-2v = 41 - 17
-2v = 24
Now, to solve for v, we divide both sides of the equation by -2:
v = 24 / (-2)
v = -12
Therefore, the solution to the equation is v = -12.
Explain why the equation 6|x| + 25 = 15 has no solution. When one solves, they arrive at a step where |x| is equal to a negative number. Since | x| can never be negative, there is no solution. When one solves, they arrive at a step where |x| is equal to a fraction that may not be represented as an integer. Since | x| must be an integer, there is no solution. When one solves, they arrive at a step where x is equal to a negative number. Since x can never be negative inside of the absolute value bars, there is no solution. The statement is false. There is a solution.
The equation 6|x| + 25 = 15 has no solution because it implies that |x| equals a negative number after simplification, and absolute values cannot be negative.
Explanation:The equation 6|x| + 25 = 15 has no solution because the absolute value of x, denoted by |x|, represents the distance of x from zero on the number line, and as such, it can never be negative. When we solve the given equation, we isolate the absolute value on one side which gives us 6|x| = -10 after subtracting 25 from both sides. Dividing by 6, we obtain |x| = -10/6, which is a negative number. However, since an absolute value cannot equal a negative number, this indicates that there is no valid solution to the equation.
The Porter family has a net income of $5,000. If they want to reduce their food budget by $50, how much would the new food budget be? $
The new food budget is $400, the difference in the savings is $50 and the amount of money saved now is $2700.
What is an Equation?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
The equations are useful in determination of unknown parameters.
The Porter family has a net income of $5000.
The food budget of the family is $450
The budget is reduced by $50
The new food budget is $450 - $50
The new food budget is $400
Initially they used to save,
= $5000 - $450- $1900
= $2650
Now as the expense has been reduced by $50,
The new savings will be,
= $2650 + $50
= $2750
It seems that your question is incomplete, the complete question is :
The Porter family has a net income of $5,000. They have a monthly food budget of $450 and $1900 is extra expenses, If they want to reduce their food budget by $50, how much would the new food budget be and what will be the difference in the savings.

The table shows the annual profits (in thousands of dollars) of a county fair from 2008 to 2012. What must the 2012 profit be (in hundreds of dollars) to break even over the five-year period?
Answer:
In year 2012, 0.45 thousands dollars will bring the break even for the company.
Step-by-step explanation:
The table shows the annual profits of a county fair from 2008 to 2012.
We have to calculate the profit in 2012 to get the break even over the five year period.
Total profit in four years = profit in year (2008 + 2009) = 2.5 + 1.75 = 4.25 thousand dollars
Total loss in four years = loss in year (2010 + 2011) = 3.3 + 1.4 = 4.7 thousand dollars
Net profit or loss = Net profit - net loss = 4.25 - 4.7 = -0.45
There is a net loss of 0.45 thousand dollars.
If we get a profit of 0.45 thousand dollars in year 2012, we will be in the situation of no profit and no loss (break even).
Therefore, profit of 0.45 thousands of dollars is the answer.

Seven years ago, kodi found a box of old baseball cards in the garage. since then, he has added a consistent number of cards to the collection each year. he had 52 cards in the collection after 3 years and now has 108 cards. kodi looking into his box of baseball cards. how many cards were in the original box? is this t(0) or t(1)? write the first few terms of the sequence. kodi plans to keep the collection for a long time. how many cards will the collection contain 10 years from now? write an equation that determines the number of cards in the collection after n years. what does each number in your rule represent?
The required equation is y = 14x + 10 which is the number of cards in the collection and he will have 150 cards after 10 years
What is the slope of the line?The slope of the line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
As per the question, we take the two points are (3,52) (7,108)
So slope = (108 - 52) / (7 - 3) = 56/4 = 14
y = mx + b
slope(m) = 14
Substitute the value of x = 3 and y = 52 in the equation
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b
So the original amount of cards is 10
If x represents the number of years, while y is the total number of cards.
y = 14x + 10
He began with 10 cards and has added 14 cards every year thereafter.
So after 10 years
y = 14(10) + 10
y = 140 + 10
y = 150
Therefore, he will have 150 cards after 10 years

34 days to 2 weeks the ratio is
The ratio of 34 days to 2 weeks is [tex]\(\frac{34}{2 \times 7}\)[/tex].
To find the ratio of 34 days to 2 weeks, we first need to convert 2 weeks into days, since there are 7 days in a week. Therefore, 2 weeks is equivalent to [tex]\(2 \times 7\)[/tex] days, which is 14 days.
Now, we can set up the ratio of 34 days to 14 days (2 weeks):
[tex]\[ \text{Ratio} = \frac{34 \text{ days}}{14 \text{ days}} \][/tex]
To simplify this ratio, we can divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 34 and 14 is 2.
Dividing both by 2, we get:
[tex]\[ \text{Ratio} = \frac{34 \div 2}{14 \div 2} = \frac{17}{7} \][/tex]
So, the simplified ratio of 34 days to 2 weeks is [tex]\(17:7\) or \(\frac{17}{7}\)[/tex].
