The product of 2, and a number increased by 6, is -24
The mathematical expression is,
⇒ 2x + 6 = - 24
And, The value of number = - 15
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Nicholas volunteers at a local soup kitchen and he notices how quickly the kitchen is going through its stock of canned goods.
It is given that a graph has number of days on the x - axis and number of canned goods on the y-axis. The line goes through points (2, 699) and (8, 321). The slope of the line can be written as -
[m] = (321 - 699)/(8 - 2)
[m] = -378/6
[m] = - 63
For the point (2, 699), we can write -
y = - 63x + c
699 = - 63 x 2 + c
699 = -126 + c
c = 699 + 126
c = 835
Therefore, the slope of the line would be - [m] = - 63 and the [y] intercept is - [c] = 835.

The given system of equations 3x-2y=12 and 6x-4y=24 has no solution.
As per the question, we have to determine the solution to the following system of equations, 3x-2y=12 and 6x-4y=24
What is the equation?The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
Here,
Given a system of the equation,
3x-2y = 12
x = 12 + 2y / 3 - - - - -(1)
6x - 4y =24 - - - - -(2)
Put the value of equation 1 in the equation
6 (12 + 2y / 3) - 4y = 24
2 (12 + 2y) - 4y = 24
24 +4y - 4y = 24
24 = 24
Thus, the given system of equations 3x-2y=12 and 6x-4y=24 has no solution.

Julia and Kim round the number of pages to the nearest hundred as 1500.
Given that, there are 1,525 pages in a book.
What is the rounding off numbers?Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
In the given number, digit in the tens place is 2, so the number rounded to nearest hundred as 1500.
Therefore, Julia and Kim round the number of pages to the nearest hundred as 1500.

Maria wants to find the product of 5 3/20 multiplied by 3 4/25 using decimals instead of fractions how can she rewrite the problem using decimals
Answer:
[tex] 5.15\times 3.16=16.2740[/tex]
Step-by-step explanation:
Maria wants to find the product of [tex]5\frac{3}{20}[/tex] multiplied by[tex]3\frac{4}{25}[/tex]
First we change mixed fraction to fraction and then change into decimal.
#First fraction:
Change mixed to fraction[tex]5\frac{3}{20}\Rightarrow \dfrac{103}{20}[/tex]
Change fraction to decimal[tex]\dfrac{103}{20}\Rightarrow \dfrac{103\times 5}{20\times 5}=5.15[/tex]
#Secondfraction:
Change mixed to fraction[tex]3\frac{4}{25}\Rightarrow \dfrac{79}{25}[/tex]
Change fraction to decimal[tex]\dfrac{79}{25}\Rightarrow \dfrac{79\times 4}{25\times 4}=3.16[/tex]
Now we find the product of both decimal
[tex]\Rightarrow 5.15\times 3.16[/tex]
Using calculator product of 515 and 316 = 162740
Both number has decimal digits two
So, total number of decimal digits is 4
In multiply result write decimal before 4 digits from right.
Therefore,
[tex] 5.15\times 3.16=16.2740[/tex]
If point a is located at coordinates (5, 3) and point b is located at coordinates (-3, 9), what is the distance from a to b if the units of the coordinated system are meters?
The distance from a to b if the units of the coordinated system are meters is 10m.
What is a line segment?A line that has two endpoints and a fixed measurement is called a line segment.
It is given that point a is located at coordinates (5, 3) and point b is located at coordinates (-3, 9)
D = √[(x-p)² + (y-q)²]
Substituting the points we get;
D = √[(-3 - 5)² + (9 - 3)²]
D = √[(-8)² + (6)²]
D = √[(64) + (36)]
D = √100
D = 10
Hence, the distance from a to b if the units of the coordinated system are meters is 10 m.

Final answer:
The distance between point A (5, 3) and point B (-3, 9) is calculated using the distance formula, resulting in a distance of 10 meters.
Explanation:
The question is asking for the distance between two points in a coordinate system. To find the distance between point A (5, 3) and point B (-3, 9), we can use the distance formula which is derived from Pythagorean theorem. The distance d between two points (x1, y1) and (x2, y2) is given by:
d = √((x2 - x1)² + (y2 - y1)²)
For point A and point B, we substitute the coordinates into the formula:
d = √((-3 - 5)² + (9 - 3)²)
= √(64 + 36)
= √100
= 10 meters
Therefore, the distance from A to B is 10 meters.
The formula for the volume of a sphere is Upper V equals four thirds pi r cubedV=

a. Find the exact volume of the sphere.
b. Find a 2-decimal-place approximation for the volume.
After calculating, the volume of the sphere obtained will be equal to V = 1.45 × 10¹⁰ mm³.
What is Volume?Every three-dimensional item takes up space in some way. The volume of this area is what is used to describe it. The area covered within an entity's three-dimensional bounds is referred to as its volume. The object's size is another name for it.
As per the given data in the question,
The formula for the volume of the sphere is given as,
V = 4/3 π r³
Diameter = 3030 mm
r = D/2
r = 3030/2
r = 1515 mm
So, the volume will be,
V = 4/3 π (1515³)
V = 1.45 × 10¹⁰ mm³

The cost of 5 cds and a $ 12 DVD
The cost of 5 CDs and a $12 DVD is $62.
Explanation:The subject of this question is Mathematics. The question asks for the cost of 5 CDs and a $12 DVD. To find the total cost, we need to know the price of each CD and the price of the DVD.
Let's say the price of each CD is $10. The total cost of 5 CDs would be 5 multiplied by $10, which is $50.Adding the cost of the DVD, which is $12, to the cost of the CDs, we get a total cost of $50 + $12 = $62.Therefore, the cost of 5 CDs and a $12 DVD is $62.

In a number of identical boxes of chocolates there are 90 dark ginger, 198 white and 126 hazelnut. What is the largest possible number of boxes of chocolates?
The problem involves finding the Greatest Common Divisor (GCD) of the three numbers. The GCD of 90, 198, and 126 is 18. Hence, the largest possible number of identical boxes of chocolates is 18.
Explanation:The problem involves finding the Greatest Common Divisor (GCD) of the three quantities to find the largest possible number of identical boxes of chocolates. The GCD is the largest number that divides all three quantities evenly. So, let's first calculate the GCD of the given quantities: 90 dark ginger, 198 white, and 126 hazelnut chocolates.
We use the Euclidean Algorithm to find the GCD. Start with the two largest numbers, 198 and 126. The remainder of 198 divided by 126 is 72. Then, divide the initial divisor 126 by this remainder 72 to get another remainder 54. Continue this process with 72 and 54 to get a remainder 18. Now, the number 18 divides 54 exactly with 0 remainder, so 18 is the GCD of 198 and 126. When we test 18 with the third number, 90, it also divides evenly, hence the GCD of all three numbers is 18.
This means that the largest possible number of identical boxes of chocolates is 18.

A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour. A blue candle is 6 inches tall and burns at a rate of 1/5 inch per hour. After how many hours will both candles be the same height?
Answer:
4 hours
Step-by-step explanation:
The height of the red candle in inches can be modeled by ...
h = 8 - (7/10)t
where t is the number of hours it burns.
Likewise, the height of the blue candle can be modeled by ...
h = 6 - (1/5)t
The heights of the two candles will be the same when one expression for height is equal to the other.
8 - (7/10)t = 6 - (1/5)t
2 = t(7/10 - 1/5) . . . . . . . . . add (7/10)t -6
2/(5/10) = t = 4 . . . . . . . . . divide by the coefficient of t
