Answer:

k/2 − 3/5

Step-by-step explanation:

To simplify the expression 2/5k - 3/5k + 1/10k, we combine the like terms and simplify the fractions. The simplified expression is -1/10k.

To simplify the expression 2/5k - 3/5k + 1/10k, we can combine like terms. Like terms have the same variable raised to the same power. In this case, the variable is 'k'. So, combining the fractions, we get:

(2/5 - 3/5 + 1/10)k

Now, let's simplify the fractions:

Therefore, the simplified expression is -1/10k.

Answer:

Negative Slope

Step-by-step explanation:

The slope is the ratio of Change in height to the change in horizontal distance. It can also be define as tangent of angle made by that line and it is find by formula, [tex]slope (m)= \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

The slope is said to be a positive slope when a line is moving from left to right, the line rises.

The slope is said to be a negative slope when a line is moving from left to right, the line falls.

Here, Let the student earns be y marks in test

and let incorrect question be x

then y₁ = 98 , y₂ = 90 and x₁ = 1 , x₂ = 5

then [tex]slope (m)= \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

[tex]slope (m)= \frac{90 - 98}{5 - 1} [/tex]

⇒ m = -2

Hence, it has negative slope.

The required expression is  x + 2y = 2 (3/2 + y) that gives the value 3.

An algebraic expression is consists of variables, numbers with various mathematical operations,

To write the algebraic expression with variable x that has a value of 3.

Let x is a variable and y is another variable,

The expression for the x equal to 3 can be written as,

x + 2y = 2 (3/2 + y)

The expression x + 2y = 2 (3/2 + y) gives the value 3.

Answer:

If you graph the data points and the points lie along a straight line then the data is linear.

Final answer:

To evaluate 5/9(f-32) when f=50, substitute 50 into the expression, simplify the bracket (50 - 32 = 18), and then multiply the result by 5/9. This simplifies to 18/9 (which is 2), and then 2 x 5, yielding a final answer of 10 degrees Celsius.

Explanation:

To evaluate the expression 5/9(f-32) when f=50, you need to plug the value of f into the expression and then simplify it.

Here are the steps:

Substitute 50 for f in the expression: (5/9) × (50 - 32).

Calculate the bracket first: 50 - 32 = 18.

Multiply the result by 5/9: (5/9) × 18.

Divide 18 by 9, which gives you 2.

Finally, multiply 2 by 5, which gives you 10.

Therefore, 5/9(f-32) evaluated at f=50 is 10 degrees Celsius.

The 5s in the number 755,371 represent different values due to their place in the number. The first 5 represents 50,000 as it is in the 'tens of thousands' place, while the second 5 represents 500 because it is in the 'hundreds' place.

The relationship between the two 5s in the number 755,371 is dictated by their place values in the number. The first 5, which is the second digit in the number, is in the 'tens of thousands' place, therefore representing 50,000. The second 5, which is the fourth digit in the number, is situated in the 'hundreds' place, therefore representing 500. Despite being the same digit, their value varies greatly because of their place in the number. This concept of

place value is crucial in understanding numbers and their values in mathematics.

To simplify the fraction 10/30, divide both the numerator and the denominator by their greatest common divisor, which is 10, resulting in the simplified fraction 1/3.

Simplifying the Fraction 10/30

To simplify the fraction 10/30, we want to find the greatest common divisor (GCD) that both the numerator (10) and the denominator (30) share. In this case, both numbers are divisible by 10. So, we divide both parts of the fraction by 10 to find the simplest form.

Step 1: Divide the numerator by 10.
10 / 10 = 1

Step 2: Divide the denominator by 10.
30 / 10 = 3

Therefore, the simplified form of the fraction 10/30 is 1/3. As we recall from our Algebra classes, this is a legal maneuver because multiplying or dividing by a fraction equivalent to 1 (like 10/10) does not change the value of the original fraction. It only simplifies it. So, the simplified fraction of 10/30 is indeed 1/3.

The slope in the equation y = 15x + 25 represents the rate at which Aaron's earnings increase per lawn mowed, which is $15 for each additional lawn.

In the equation y = 15x + 25, the slope is represented by the coefficient of x, which is 15. The slope indicates the rate at which Aaron's total earnings increase for each additional lawn he mows. Specifically, the slope value of 15 means that Aaron earns $15 for each lawn he mows. The y-intercept of the equation is 25, which represents a starting value or a fixed amount that does not depend on the number of lawns mowed. This indicates that Aaron might have a base charge or initial fee of $25 before he starts mowing any lawns.

The slope in the equation y = 15x + 25 indicates Aaron earns $15 for each lawn he mows. The slope is the rate of change between lawns mowed (independent variable) and money earned (dependent variable).

The slope in the equation y = 15x + 25 represents the amount of money Aaron earns per lawn he mows. In this equation, the slope is 15, which means that Aaron earns $15 for each lawn he mows. The y-intercept in this context is 25, which typically would represent an initial fee or starting amount, but since it relates to lawns mowed, it may not have a contextually relevant interpretation without additional information. In general, the slope in a linear equation like this contextualizes the rate of change between the independent variable (lawns mowed) and the dependent variable (total money earned).
