It is feasible to use contrasting words and expressions. Any mathematical statement containing variables, numbers, and a mathematical action between them is known as an expression, often known as an algebraic expression. As an example, the expression 4m + 5 is composed of the expressions 4m and 5, as well as the variable m from the above equation, which are all separated by the mathematical symbol +.
We must take the time they spent at the mall overall from the moment they departed in order to determine when Ariana and Leon began looking for clothing.
To make adding up the times easier, let's first convert all the times to minutes:
Clothing shopping takes an hour, or 60 minutes.
Restaurant: 55 minutes
In a video arcade, two hours are equal to 120 minutes plus 10 minutes.
Total time spent at the mall is 245 minutes (60 + 55 + 130).
If they left the mall at 1:40, then we need to take 245 minutes away from that time.
1:00 PM minus 245 minutes equals 10:35 AM.
As a result, around 10:35 AM, Ariana and Leon began their clothing shopping.

This can be resolved with d = 25 miles by multiplying equation both sides by
Which equation can be used to find d?If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:
15 = (3/5) * d
To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:
15 * (5/3) = d
Simplifying the expression on the left side, we get:
25 = d
Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.
In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:
15 = (3/5) * d
Which can be solved for d by multiplying both sides by 5/3, giving:
d = 25 miles

What are functions ?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
What are asymptotes ?
An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.
An asymptote of the curve y = f(x) or in the implicit form: f(x,y) = 0 is a straight line such that the distance between the curve and the straight line lends to zero when the points on the curve approach infinity.
There are three types of asymptotes namely:
1) Vertical Asymptotes
2) Horizontal Asymptotes
3) Oblique Asymptotes
The point to note is that the distance between the curve and the asymptote tends to be zero as it moves to infinity or -infinity.

In a group of 15 children, 5 said they are an only child, 3 said they have 1 sibling only, 4 said they have exactly 2 siblings, and 3 said they have exactly 3 siblings.
What is the average number of siblings for this group?
Enter your answer as a decimal, rounded to the nearest tenth, in the blank.
Answer:
1.3
Step-by-step explanation:
To find the average number of siblings for the group, we need to calculate the total number of siblings and divide by the total number of children.
Out of the 15 children:
5 are only children, so they have 0 siblings each.
3 have 1 sibling each, so there are 3 * 1 = 3 siblings in total.
4 have 2 siblings each, so there are 4 * 2 = 8 siblings in total.
3 have 3 siblings each, so there are 3 * 3 = 9 siblings in total.
The total number of siblings is 0 + 3 + 8 + 9 = 20.
The average number of siblings for the group is 20/15 = 1.3 (rounded to the nearest tenth).
Therefore, the average number of siblings for this group is 1.3.

Solve the system of equations below, using the technique of your choice.
x+y=8
-x+4y= 2
The solution to the system of equations is x = 6 and y = 2.
The system of equations can also be solved using the elimination method.
what is the elimination method?We are aware that a system of linear equations is a collection of two or more equations with at least two unknown variables. Finding the answers to the unknown variables in a system of equations is the process of solving a linear equation. There are numerous ways to identify the answers to the unknown variables. These include the cross-multiplication method, elimination method, substitution method, and graphic method.
from the question:
A system of equations can be solved in a variety of methods, including substitution, elimination, and matrices. I'll apply the substitution technique here:
x = 8 - y is the result of the first equation.
We can solve for y by substituting this expression for x in the second equation:
-x + 4y = 2
-(8 - y) + 4y = 2 (substituting x = 8 - y)
-8 + 5y = 2 (simplifying)
5y = 10 (adding 8 to both sides)
y = 2 (dividing by 5)
Knowing y, we can now use this quantity to solve one of the initial equations to determine x:
x + y = 8
x + 2 = 8 (substituting y = 2)
x = 6 (subtracting 2 from both sides)
Hence, x = 6 and y = 2 are the answers to the system of equations.

By answering the above question, we may state that John consequently variable sold 35 notepads.
What is a Variable?A variable is anything that may be altered in the context of an experiment or mathematical idea. A single symbol is frequently used to denote a variable. Generic symbols for variables are the letters x, y, and z. Variables are qualities with a wide range of values that may be investigated. These include characteristics like height, age, wealth, place of birth, academic standing, and kind of residence, to mention a few. The two primary groups of variables can be separated using numerical and categorical approaches.
Let's define the variables first:
Let's call John's sales of notebooks "n" the quantity.
Each notebook costs $1.50, hence the whole profit from notebook sales is $1.50.
John earned a total of $92.50, according to the issue, thus we can create the following equation:
$40.00 + 1.5n = $92.50
Now that "n" is solved, we can:
$1.5n = $92.50 - $40.00
$1.5n = $52.50 \sn = 35
John consequently sold 35 notepads.

How to find the number of tilesIf Jenny arranges the tiles in a rectangular array with 4 rows, this means each row will have 50/4 = 12.5 tiles. However, since we cannot have half a tile, we need to round down to the nearest whole number, which is 12.
Therefore, each row will have 12 tiles, and the total number of tiles used will be 4 x 12 = 48. To find out how many tiles are left over, we need to subtract the total number of tiles used from the original number of tiles: 50 - 48 = 2. So, there will be 2 tiles left over.

For what value of k will V= x+ k/x have a relative minimum at x = 3?
The value of k will make V = x + k/x have a relative minimum at x = 3 is k = 9
What is a relative minimum?A relative minimum of a function is the minimum value of the function in a particular interval.
Since we have the function V = x + k/x. We desire to find the value of k that will make V = x + k/x have a relative minimum at x = 3
So, to find the relative minimum of V, we differentiate with respect to x and equate to zero.
So, V = x + k/x
dV/dx = d(x + k/x)/dx
= dx/dx + kd(1/x)/dx
= 1 - k/x²
Equating dV/dx to zero, we have that
dV/dx = 0
⇒ 1 - k/x² = 0
1 = k/x²
k = x²
For a relative minimum at x = 3, substitute x = 3 into the equation. So, we have that
k = x²
= 3²
= 9
So, k = 9
