Sam is 3 years younger than Marco. Marco is 15 years old. How old is Sam? Let X represent Sam's age (there are 2 correct answers)
x + 15 = 3
x + 3 = 15
15 divided by x = 3
3 x = 15 15 - x = 3
thanks
Correct options are:
X+3=15
and 15-X=3
Step-by-step explanation:Sam is 3 years younger than Marco.
Let X represent Sam's age
Then, Marco's age=X+3
Marco is 15 years old.
i.e. X+3=15
or 15-X=3
Hence, Correct options are:
X+3=15
and 15-X=3

Water weighs 8.34 pounds per gallon. How many ounces per gallon is the weight of the water
a number where 3 is worth 1/10 as much and 2 is worth 10 times as much as the number 431, 621
The question pertains to exponential notation in our decimal numbering system, where each place is worth ten times the next right place. It creates a more convenient way to express very large or small numbers. The rules of multiplication in this system involve multiplying the numbers out front and adding the exponents.
Explanation:
The question refers to place value in a number, where we are told how much each digit is worth based on their position. Here, '3' is worth 1/10 as much and '2' is worth 10 times as much as the number 431, 621. The power (exponent) of 10 is equal to the number of places the decimal is shifted to give the digit number.
This is part of exponential notation, which is especially useful for very large and very small numbers. For instance, 1,230,000,000 can be written as 1.23 × 10⁹, and 0.00000000036 can be articulated as 3.6 × 10-¹0. It's called powers-of-ten notation because each place in our numbering system is ten times greater than the place on its right.
To compute this, we use a method where we multiply the numbers out front and add the exponents. For instance, (3 × 10⁵) × (2 × 10º) equals 6 × 10⁵. This notation not only simplifies arithmetic but is also compact and convenient.

An acute triangle has sides measuring 10cm and 16 cm. The length of the third side is unknown. Which best describes the range of possible values for the third side of the triangle?
Answer:
The range of possible values for the length of the third side of the triangle is [tex]\( 6 < x < 26 \)[/tex], meaning that the third side must be greater than 6 cm and less than 26 cm.
Explanation:
To determine the range of possible values for the third side of the triangle, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Let's denote the length of the third side as [tex]\( x \)[/tex]. According to the triangle inequality theorem:
1. The sum of the lengths of the two given sides (10 cm and 16 cm) must be greater than the length of the third side:
[tex]\[ 10 + 16 > x \][/tex]
[tex]\[ 26 > x \][/tex]
2. The length of the third side must be greater than the difference of the lengths of the two given sides:
[tex]\[ 16 - 10 < x \][/tex]
[tex]\[ 6 < x \][/tex]
Combining both inequalities, we have:
[tex]\[ 6 < x < 26 \][/tex]

what is 4.1363636… as a fraction?
Answer:
x = [tex]\frac{819}{598}[/tex].
Step-by-step explanation:
Given : 4.1363636…
To find : Convert it as fraction .
Solution : We have given 4.1363636…
Let x = 4.1363636…
On multiplying both sides by 100
100 x = 100 * 4.1363636…
100 x = 413 .63636...
We can convert it in term of x
100 x = 409 .5 + 4.1363636...
100 x = 409.5 + x
On subtracting both sides by x
100 x -x = 409.5
99 x = 409. 5
On dividing both sides by 99
x = [tex]\frac{409.5}{99}[/tex].
x = [tex]\frac{4095}{990}[/tex].
On dividing both sides by 5
x = [tex]\frac{819}{598}[/tex].
Therefore, x = [tex]\frac{819}{598}[/tex].
Show that each number is a rational number by expressing it as a ratio of two integers
A. 27
B. .075
C. 4 2/3
D. -9
E. 0.43
F. -18
Each number provided is a rational number, as they can all be expressed as a ratio of two integers. Therefore, they all qualify as rational numbers.
Explanation:In Mathematics, a rational number is a number that can be expressed as a ratio of two integers. An integer is a whole number that can be positive, negative, or zero. Let's express each number given as a ratio of two integers:
A. 27 can be expressed as 27/1. B. 0.075 can be expressed as 75/1000. C. 4 2/3 can be expressed as 14/3 (since 4 2/3 equals to 4 + 2/3 = 12/3 + 2/3 = 14/3). D. -9 can be expressed as -9/1. E. 0.43 can be expressed as 43/100. F. -18 can be expressed as -18/1.
As you can see, each of these numbers can be written as a ratio of two integers, thus they are all rational numbers.

Each given number (27, 0.075, 4 2/3, -9, 0.43, and -18) is shown to be a rational number by expressing it as a ratio of two integers, such as 27/1, 3/40, 14/3, -9/1, 43/100, and -18/1, respectively.
To show that a number is a rational number, we must express it as a ratio of two integers.
27 can be expressed as 27/1 which is the ratio of two integers (27 and 1).0.075 can be written as 75/1000 which simplifies to 3/40 after dividing both the numerator and the denominator by 25.4 2/3 is 4 + 2/3 and can be written as 14/3 which is a combination of an integer and a fraction representing the ratio of two integers (14 and 3).-9 can be written as -9/1 which shows the number -9 as a ratio of two integers (-9 and 1).0.43 is equivalent to 43/100 and therefore can be expressed as the ratio of two integers (43 and 100).-18 can be written as -18/1 which is a ratio of two integers (-18 and 1).What is one times one times four times twelve divided by three divided by two times nine minus twelve divided by twelve times one hundred twenty-three million, four hundred fifty-six thousand, seven hundred eighty-nine?

A restaurant buys eggs in cases of 15 dozen eggs per case. The owner of the restaurant specializes in omelettes. He ordered three cases of eggs per day just for omelettes if H only contains four eggs, how many hours can be made from three cases of eggs?
135 omelettes can be made from three cases of eggs.
To find out how many omelettes can be made from three cases of eggs, we first need to calculate the total number of eggs in three cases.
Each case contains 15 dozen eggs, and since a dozen is 12 eggs, one case contains [tex]\(15 \times 12 = 180\)[/tex] eggs.
So, three cases would contain [tex]\(3 \times 180 = 540\)[/tex] eggs.
Now, if each omelette requires four eggs, we can find out how many omelettes can be made:
[tex]\[ \text{Number of omelettes} = \frac{\text{Total number of eggs}}{\text{Number of eggs per omelette}} \][/tex]
[tex]\[ \text{Number of omelettes} = \frac{540}{4} \][/tex]
[tex]\[ \text{Number of omelettes} = 135 \][/tex]
