Final answer:

To find the value of x in the equation x+3.75=11 1/3, convert the mixed number to an improper fraction, subtract and find a common denominator, and solve for x. The solution to the equation is x is approximately 7.5833 or rounded to 7.58.

Explanation:

To solve for x in the equation x+3.75=11 1/3, we first need to convert the mixed number 11 1/3 to an improper fraction. To do this, multiply the whole number by the denominator of the fraction and add the numerator. In this case, (11×3)+1 equals 34, so 11 1/3 is the same as 34/3.

Next, subtract 3.75 from both sides to isolate x on one side of the equation:

x + 3.75 = 34/3

x + 3.75 - 3.75 = 34/3 - 3.75

x = 34/3 - 3.75

To subtract, first convert 3.75 (which is the same as 3 3/4 or 15/4) to an improper fraction, so we get:

x = 34/3 - 15/4

We need a common denominator to subtract these two fractions. The common denominator of 3 and 4 is 12. Multiply the numerator and denominator of the first fraction by 4 and the numerator and denominator of the second fraction by 3 to get:

x = (34×4)/(3×4) - (15×3)/(4×3)

x = 136/12 - 45/12

x = (136 - 45)/12

x = 91/12

x = 7.5833...

Finally, x is approximately 7.5833, which can be rounded to 7.58 if necessary.

Answer:

1) Twenty-one halves of one-thirds are in seven halves.

2) Fourteen-thirds of three-fourths are in five halves.

Step-by-step explanation:

1) To find : How many one-thirds are in seven halves?

Solution :

Let the required number be 'x',

According to question,

[tex]\frac{1}{3}\times x=\frac{7}{2}[/tex]

Solving the equation,

[tex]x=\frac{7\times 3}{2}[/tex]

[tex]x=\frac{21}{2}[/tex]

Therefore, Twenty-one halves of one-thirds are in seven halves.

2) To find : How many three-fourths are in five halves?

Solution :

Let the required number be 'x',

According to question,

[tex]\frac{3}{4}\times x=\frac{5}{2}[/tex]

Solving the equation,

[tex]x=\frac{7\times 4}{2\times 3}[/tex]

[tex]x=\frac{14}{3}[/tex]

Therefore, Fourteen-thirds of three-fourths are in five halves.

Daniel has [tex]16[/tex] pets.

Since six of his pets are birds(canaries and parrots and he has two parrots, therefore, he has (6 - 2) = 4 canaries.

Since he has one less canary than goldfish, therefore the number of goldfish is (6 + 1) = 7 goldfish

Since he has four more goldfish than he has turtles, the number of turtles are: = ( 7 - 4) = 3

Therefore, the total number of animals will be:

= Parrot + Canary + Goldfish + Turtle

= [tex]2 + 4 + 7 + 3[/tex]

= [tex]16[/tex]

Therefore, he has [tex]16[/tex] pets.

Step-by-step explanation:

Answer:

360

Step-by-step explanation:

To solve this problem, establish an algebraic equation that equates the sum of the lengths of the three pieces to the total length of the board. Solving this equation reveals that the first piece of wood is 5 inches, the second piece 20 inches and the third piece 25 inches.

This question represents a simple algebraic equation. Since the second piece is 4 times the length of the first piece and the third piece is 5 times the length of the first piece, the sum of these lengths should equal the total length of the board, which is 50 inches. Given that 'x' represents the length of the first piece, we can establish the following equation:

x + 4x + 5x = 50

This is because '4x' is the length of the second piece and '5x' is the length of the third piece. When you combine like terms, the equation simplifies to:

10x = 50

Upon solving this simplified equation, we find that 'x' or the length of the first piece of wood equals 5 inches. Therefore, based on the information provided, the length of the second piece would be 20 inches (4 times 'x') and the third piece would be 25 inches (5 times 'x').

Answer:

2n - 1, where "n" is the number of days.

Step-by-step explanation:

By looking at the bar graph.

We list the following information.

Day           The number of followers

1                            1

2                          3

3                          5

4                          7

So, the number of followers increase by 2 each day passes.

This is an arithmetic sequence.

The sequence is 1, 3, 5, 7.....

So the rule [tex]a_n = a_1 + (n -1)d[/tex]

This is the n-term of the arithmetic sequence.

Here [tex]a_ 1 = 1 and d = 2[/tex] and n is the number of days.

Plug in these values in the above sequence, we get

The general rule = 1 + (n -1)2

= 1 + 2n-2

= 2n - 1

So the general rule = 2n - 1

Step-by-step explanation:

scientific notation is the standard form of writing numbers in a particular format

scientific notation is writing a number between 0 and 10 times a power of 10

the number to be written is 427 000

so we need to get the decimal point after the first digit from the right

decimal point should come to the right of digit 4

for the decimal to come next to 4 it has to move 5 places to the left. Then its 4.27 multiplied by 10⁵

scientific notation is - 4.27 x 10⁵

Based on the information given 427 thousand as scientific notation is:4.27 x 10⁵.

Scientific notation is the way of writing or expressing number in simplest form.

4.27 x 10⁵=4.27×10×10×10×10×10

4.27 x 10⁵=427,000

Scientific expression=4.27 x 10⁵

Inconclusion  427 thousand as scientific notation is:4.27 x 10⁵.

The number of wrenches is 10 for which he paid $1.50, and $2.50. the number of wrenches is 5 for which he paid $4, and the number of wrenches is 6 for which he paid $3.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have:

Mr. Abernathy bought a selection of wrenches for his shop and paid $78.

Let's suppose:

The number of $1.50 wrenches is x

The number of $2.50 wrenches is also x

The number of $4 wrenches is x/2

The number of $3 wrenches is 1+x/2

Then linear equation becomes:

[tex]\rm 1.50x+2.50x+\frac{4x}{2} +3(1+\frac{x}{2} ) = 78[/tex]

[tex]\rm 3x+5x+4x +3(2+x ) = 156[/tex]

15x = 150

x = 10

The value of x = 10

=x/2 ⇒ 10/ 2 ⇒ 5

= 1+x/2 ⇒ 1+5 ⇒ 6

Thus, the number of wrenches is 10 for which he paid $1.50, and $2.50. the number of wrenches is 5 for which he paid $4, and the number of wrenches is 6 for which he paid $3.

Final answer:

The y-intercept is the value of y when x is zero, represented by the constant b in the linear equation y = mx + b. In the example y = 55x + 75, the y-intercept is 75, indicating where the line intersects the y-axis and signaling the initial value of y before any changes in x.

Explanation:

An example of a y-intercept can be found in the linear equation y = mx + b, where b represents the y-intercept. This value is where the line crosses the y-axis on a graph. If we consider the equation y = 55x + 75, for instance, the y-intercept is 75. This means that when x (the independent variable) is zero, the y value, possibly indicating the starting point of a scenario such as labor charges before work begins, is 75.

A real-world example can be seen in a car repair scenario where the total labor charges (y) depend on the number of hours worked (x). Given the equation y = 55x + 75, when no hours are worked (x=0), the total charges start at $75, which is the y-intercept. The slope of the line is 55, indicating that for each additional hour worked, the labor charges increase by $55.

The answer is x=-1.

Add 5x on both sides.

10x=-10

Divide both sides by 10.

x=-1.

Final answer:

An even number is divisible by 2, while an odd number is not. Examples of even numbers are 8 and 10, while examples of odd numbers are 17 and 21.

Explanation:

An even number is a number that is divisible by 2, while an odd number is not divisible by 2.

For example, 2, 4, and 6 are even numbers because they can be divided by 2 without leaving a remainder. On the other hand, 3, 5, and 7 are odd numbers because they cannot be divided by 2 without leaving a remainder.

So, two examples of even numbers could be 8 and 10, while two examples of odd numbers could be 17 and 21.
