combine like terms to simplify the expression 2/5k-3/5k+1/10k
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.
Explanation: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.

A chef had to fill up 4/5 of a container with mash potatoes. He ended up using 2 4/6 pounds of mashed potatoes. How many pounds would he need to fill the container all the way
Answer: He would need [tex]3\dfrac{1}{3}[/tex] pounds to fill the container all the way.
Step-by-step explanation:
Since we have given that
Fraction of mashed potatoes he had to fill up a container = [tex]\dfrac{4}{5}[/tex]
Fraction of mashed potatoes he ended up using = [tex]2\dfrac{4}{6}=2\dfrac{2}{3}=\dfrac{8}{3}[/tex]
So, we need to find the number of pounds that he would need to fill the container all the way.
So, number of pounds would be
[tex]\dfrac{8}{3}\div \dfrac{4}{5}\\\\=\dfrac{8}{3}\times \dfrac{5}{4}\\\\=\dfrac{10}{3}\\\\=3\dfrac{1}{3}[/tex]
Hence, he would need [tex]3\dfrac{1}{3}[/tex] pounds to fill the container all the way.

Which rational numbers is not equivalent to the others. 75%,3/4,0.75,7/50
The rational number 7/50 is not equivalent to the other numbers listed (75%, 3/4, 0.75) as it converts to a decimal value of 0.14, which is distinct from 0.75.
Explanation:The question asks which rational number is not equivalent to the others: 75%, 3/4, 0.75, or 7/50. To determine this, we can convert all the numbers to a common format, such as decimals or fractions, and compare their values.
First, 75% is equivalent to 0.75, as percent means "per hundred," so 75% is 75 per 100, which can be written as 75/100 and simplified to 3/4 or 0.75. Next, 3/4 is exactly 0.75 when converted to a decimal. This means that these three are equivalent to each other.
However, 7/50 is a different case. When we convert 7/50 to a decimal, we get 0.14, which is evidently different from 0.75. Therefore, 7/50 is not equivalent to the other rational numbers listed.

Lars bought 3 jars of marbles. Each jar has 42 marbles, of which 13 are red. Lars can use the calculation below to find the total number of red marbles. 3×(13×42)
Answer: (3x1/3) x 42
Step-by-step explanation: trust me I took the test.
There are total 1638 marbles.
What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Number of jars = 3
Each bar contain = 42 marbles
Red marbles = 13
So, total number of marbles
= 3 x 13 x 42
= 1638.
Hence, there are total 1638 marbles.

A student earns a 98 on a test for answering one question incorrectly and earns a 90 for answering five questions incorrectly. Is the slope of the line that models the linear relationship a positive negative zero or undefined slope?
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 table below shows some properties of regular polygons.
When compared with the independent variable, how many of the remaining three columns represent a linear relationship?
A. 0
B. 1
C. 2
D. 3
Answer: C.2
Step-by-step explanation:
Given: Independent variable= Number of sides
To check how many of the remaining three columns represent a linear relationship, we need to check the rate of change of the three columns with respect to dependent variable.
For number of diagonals
The rate of change of diagonals w.r.t number of sides is constant and that is 1.
For Sum of all interior angles (degrees)
The rate of change of Sum of all interior angles w.r.t number of sides is constant and that is 180°.
For measure of each angle (degrees)
The rate of change of measure of each angle w.r.t number of sides is not constant and that is 180°.
Since for vertices 3 , measure of angle=60
vertices 4 , measure of angle=90
From vertices 3 to 4 change in measure of angle is 30
vertices 5 , measure of angle=108
From vertices 4 to 5 change in measure of angle is 18
Thus number of diagonals and Sum of all interior angles are the columns represent a linear relationship when compared with the independent variable.
Therefore there are 2 columns represent a linear relationship when compared with the independent variable.
Solution:
The equation of linear relationship is , y= k x
That is, [tex]\frac{y-value}{x-value}=k({\text{a constant})[/tex]
As, you can see that , ratio of
1.
[tex]\frac{\text{Sum of interior angles of a regular polygon}}{\text{number of sides of that polygon}}={\text{Measure of each interior angle of regular polygon}}[/tex]
2. Also, as number of sides increases, the smallest regular polygon is equilateral triangle(3 sides) , having 0, diagonal, the number of diagonal increases by 1.
→→Regular polygon having sides , n≥3=k, where k is number of diagonals=0,1,2,3,4,[ For example, for, n=3,k=1,n=4, k=2,...]
Column (2)
[tex]C_{4}-C_{3}=C_{3}-C_{2}=C_{2}-C_{1}=1[/tex]
Column (4)
[tex]C_{2}-C_{1}=90-60=30\\\\ C_{3}-C_{2}=108-90=18\\\\ C_{4}-C_{3}=120-108=12[/tex]
Column (3)
[tex]C_{4}-C_{3}=720-540=180\\\\ C_{3}-C_{2}=540-360=180\\\\ C_{2}-C_{1}=360-180=180[/tex]
In, Column (2) and Column(3) the difference between two consecutive values is same, while in column (4) difference between two consecutive values is not same.So, C(2) and C(3) shows linear relationship, column (4) do not.
Option (C) 2 is Right choice.
