2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
1 - (2 • k) 1 - 2k
——————————— = ——————

6.1 Subtracting a whole from a fraction

7.1 Subtracting a whole from a fraction
3 + 2 • k 2k + 3
————————— = ——————
k k
8.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2 2 • k
2 = — = —————
1 k
9.1 Pull out like factors :
2 - 2k = -2 • (k - 1)
10.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-2•(k-1)
———————— • k = 0 • k
k
Now, on the left hand side, the k cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-2 • (k-1) = 0
Equations which are never true:
10.2 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
10.3 Solve : k-1 = 0
Add 1 to both sides of the equation :
k = 1
Step-by-step explanation:
Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1
Equations and expressionsGiven the equation expressed as
5−k+12=16
We need to find the value of "k" that will make the equation equal
Given
5−k+12=16
Collect the like terms
17 - k = 16
Subtract 17 from both sides
17 - k - 17 = 16 - 17
k = 16 - 17
k = -1
Hence the value of k that will make the equation true is -1

Answer:
18x + 6 = 2( 9x + 3 )
18x + 6 = 3( 6x + 2 )
18x + 6 = 6( 3x + 1 )
Step-by-step explanation:
Answer:
1. 2(9x+3)
2. 3(6x+2)
3. 6(3x+1)
Step-by-step explanation:
Okay so in the first one there is a 2 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 2.
9x*2=18x
3*2=6
18x+6=2(9x+6)
Okay so in the second one there is a 3 outside of the parentheses which means we will multiply whatever is onside of the parentheses by 3.
6x*3=18x
2*3=6
18x+6=3(6x+2)
Okay so in the third one there is a 6 outside of the parentheses which means we will multiply whatever is inside of the parentheses by 6.
3x*6=18x
1*6=6
18x+6=6(3x=1)
Riley goes to a store an buys an item that costs x dollars. She has a coupon for 10% off, and then a 8% tax is added to the discounted price. Write an expression in terms of x that represents the total amount that Riley paid at the register.
Answer:
0.972x
Step-by-step explanation:
x - 0.1x + 0.08(0.9x)
Converting percentages to decimals has you divide the percentage by 100.
So our first equation is full price minus a tenth of that price, leaves you with nine tenths, right? Then we multiply that nine tenths by 8 percent, which is 8 hundredths.
0.9x + 0.072x = 0.972x
Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

how can you find the vertex of a parabola if you know it's focus and directrix? in my equation, the focus is (6,4) and the directrix is y=-2
Answer:
The vertex would be (6,1)
Step-by-step explanation:
The vertex is the midway between the focus and the directrix. The X of the vertex would be the same but to get the Y of the vertex you would need to take the average of the Y values. (6, 4 + (-2)/2) (6,1)

A survey revealed that 20% of workers at a company were satisfied with their job. If 30 workers selected this option. How many total workers are at the company? Use the model below to help you solve the question.
Answer:
150 workers are at the company
Step-by-step explanation:
If 20% of the workers is equal to 30 workers than in order to find 100% of the worker you need to multiply the percentage with a number that makes it 100% and then multiply that number to the 30 workers so
20% * 5 = 100%
30 * 5 = 150
so 100% of the workers is equal to 150 workers
