Kelly bought a total of 1500 pencil boxes.
theodore goes to a baseball game and buys 3 water that cost x dollars each and a bag of popcorn for $4.50 write an expression in simplest form that reprsent the total amount if money therdore spent
What is the error 3x+4.50x
7.50 x
the experssion to find the total amount of money theodore is spent 7.50x
The answer to this question is as follows It's vital to keep in mind that equation while this is the same phrase you used, the x only applies to the cost of the water and not the cost of the popcorn.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
The formula to calculate Theodore's overall spending is:
3x + 4.50
This is due to the fact that he purchased three waters at a cost of x each, for a total cost of x, and a bag of popcorn at a cost of $4.50. The entire amount of money he spent may be calculated by adding these two expenses.
By condensing the formula 3x + 4.50, we obtain:
7.50x
It's vital to keep in mind that while this is the same phrase you used, the x only applies to the cost of the water and not the cost of the popcorn.

What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is a scatter plot as shown in the image.
We can write the equation of the line of best fit as -
{m} = (400 - 0/(60 - 40)
{m} = 400/20
{m} = 20
We can write the y - intercept as -
y = 20x + c
0 = 800 + c
c = - 800
So, the equation of the line of best fit is -
y = 20x - 800
For {y} = 5000, we can write -
5000 + 800 = 20x
5800 = 20x
x = 5800/20
x = 290

The mean age of a family of seven is 23 years. The median is 16 years, the modes are 12, years and 45 years, and the range is 35 years. Find the ages of the seven family members
Let's use the given information to set up equations to solve for the ages of the family members.
We know that the mean age of the family is 23 years, so we can write:
(sum of ages) / 7 = 23
sum of ages = 161
We also know that the median age is 16 years, which means that the ages of the family members can be arranged in order from smallest to largest, and the middle age (or the average of the two middle ages, if there are an even number of ages) is 16. We can use this information to set up an equation:
(3rd smallest age + 4th smallest age) / 2 = 16
3rd smallest age + 4th smallest age = 32
Next, we know that the range of the ages is 35 years, which means that the difference between the largest age and the smallest age is 35. We can use this information to set up another equation:
largest age - smallest age = 35
Finally, we know that the modes (the most common ages) are 12 years and 45 years. This means that there are two family members whose ages are 12 years and two family members whose ages are 45 years. We can use this information to set up two more equations:
number of 12-year-olds + number of 45-year-olds = 4
12 x number of 12-year-olds + 45 x number of 45-year-olds = sum of ages
We now have five equations and five unknowns (the ages of the seven family members). We can solve for these unknowns using algebra. One possible set of ages that satisfies all of the equations is:
2, 2, 12, 16, 20, 45, 64
(Note that the ages do not have to be integers, but this particular set of ages happens to be integers and satisfies all of the given conditions.)
2nd attempt at getting a pair of tens?
The probability of getting a pair of 10s is 1/26.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Here,
Total number of outcomes = 52
Number of outcomes = 2
So, the probability is 2/52
= 1/26
Therefore, the probability of getting a pair of 10s is 1/26.

Handheld consoles are the most at risk of being discontinued compared to other types of consoles.
option A.
Which type of console is most at risk of being discontinued?Handheld consoles have faced tough competition from the rise of mobile gaming on smartphones and tablets, which has impacted their market share and sales.
For example, Nintendo has faced challenges with their handheld consoles, such as the Nintendo DS and 3DS, which experienced a decline in sales due to the emergence of mobile gaming. As a result, Nintendo shifted its focus to the hybrid console, the Nintendo Switch, which can be used as both a handheld and home console.
That being said, it's important to note that the market for handheld consoles is still significant, and there are still popular handheld devices on the market such as the Nintendo Switch Lite and Sony's PlayStation Vita. The entertainment, interactive, and computer console markets also have their own unique challenges and opportunities, and each type of console has its own risks and benefits.

If the quarterly interest at 10.5% is $3,150, the principal amount of a loan is
The principal amount of the loan is $1,200,000.
What is simple interest?
Simple interest is the amount of borrowing-related interest that is computed using only the initial principal and a constant interest rate.
To find the principal amount of a loan, we need to use the formula for simple interest:
I = Prt
Where I is the interest, P is the principal, r is the interest rate as a decimal, and t is the time in years.
In this case, we know that the interest is $3,150 and the interest rate is 10.5%. We also know that the interest is earned quarterly, so the time period is 1/4 of a year, or 0.25 years.
Substituting these values into the formula, we get:
3150 = P * 0.105 * 0.25
Solving for P, we get:
P = 3150 / (0.105 * 0.25) = $1,200,000
Therefore, the principal amount of the loan is $1,200,000.

When Mr Lee puts an equal number of apples into 8 boxes, he has an apple left. When he puts the same number of apples into 5 boxes, he has 7 apples left. How many apples does he have?
Answer:
Let's suppose that Mr. Lee puts "x" apples into each box.
According to the first statement, when he puts an equal number of apples into 8 boxes, he has one apple left. This can be represented by the equation:
8x + 1 = n, where n is the total number of apples Mr. Lee has.
Similarly, the second statement says that when he puts the same number of apples into 5 boxes, he has 7 apples left. This can be represented by the equation:
5x + 7 = n
Now we have two equations with two unknowns (x and n). We can solve for x by setting the two equations equal to each other:
8x + 1 = 5x + 7
Subtracting 5x from both sides, we get:
3x + 1 = 7
Subtracting 1 from both sides, we get:
3x = 6
Dividing both sides by 3, we get:
x = 2
So Mr. Lee puts 2 apples into each box. To find the total number of apples he has, we can substitute x = 2 into either of the two equations we started with:
8x + 1 = 8(2) + 1 = 17
So Mr. Lee has 17 apples

Given is the system of equations as shown in the image.
{ 1 } -
x - 2y = - 7
2x + 5y = 8
We can write -
x = 2y - 7
Now -
2(2y - 7) + 5y = 8
4y - 14 + 5y = 8
9y = 22
{y} = 22/9
x = 44/9 - 7
x = 44/9 - 63/9
{x} = - 19/9
{ 2 } -
5x - 3y = 16
3x + 6y = 18
We can write -
5x - 3y = 16
x + 2y = 9
So -
x = 9 - 2y
5(9 - 2y) - 3y = 16
45 - 10y - 3y = 16
45 - 13y = 16
45 - 16 = 13y
13y = 29
y = 29/13
x = 9 - 58/13
x = 117/13 - 58/13
x = 59/13

look at the triangles below. Choose true or false for each of the statements about them. A value of x = 16 results in congruent triangles. A value of x = 27 results in congruent triangles. A value of x = 31 does not result in congruent triangles.
Answer: Without a visual representation of the triangles, it's difficult to determine whether the statements are true or false.
However, in general, the side lengths of a triangle determine its shape and size. If two triangles have the same side lengths, then they are congruent, meaning they have the same shape and size. Therefore, if the triangles in question have different side lengths for x = 16, x = 27, and x = 31, then it's possible that the statements are either true or false, depending on the specific side lengths.
Without additional information, it's not possible to determine whether the statements are true or false.
