Answer:
k = -1
Step-by-step explanation: 6-4 = k-3k
subtract: 2 = -2k
divide both sides by -2: k = -1
simplifying is easy! we simply add or subtract like terms on each side.
6-4=2
1-3=-2 and then add k which is the variable so -2k
The equation would be 2=-2k and then we can divide both sides by -2 to isolate the variable to get -1=k
Do the points shown represent additive inverses? Explain why or why not.
A number line going from negative 5 to positive 5. Points are at negative 3 and positive 3.
Answer:
Yes.
Step-by-step explanation:
W
The additive is what you add to a number to get zero.
The negative of a number.
Example:
The additive inverse of −5 is +5, because −5 + 5 = 0
The additive inverse of +5 is −5, because +5 − 5 = 0
Additive inverses are negated numbers.
The points on the number line are additive inverses.
For a number x, the additive inverse is -x.
The first point on the number line is:
[tex]\mathbf{x = 3}[/tex]
Negate both sides
[tex]\mathbf{-x = -3}[/tex]
-3 represents the additive inverse of 3.
Hence, the points on the number line are additive inverses.

data?
OA) 65 mi. per day
OB) 73 mi. per day
OC) 82 mi. per day
OD) 94 mi. per day
Answer:73
Step-by-step explanation:
The MEAN in math means you add all of the numbers together
60 plus 65 plus 73 plus 82 plus 85 = 365
then you divide how many numbers there are and there is 5 numbers so you divide.
365 divided by 5 equals 73

(solve triangles using the law of sines)
Answer:
[tex]B=51[/tex]°
Step-by-step explanation:
Use the Law of Sines as follows:
[tex]\frac{sinC}{c} =\frac{sinB}{b}[/tex]
Insert the appropriate values:
[tex]\frac{sin100}{14} =\frac{sinB}{11}[/tex]
Isolate B. Multiply both sides by 11:
[tex]11*(\frac{sin100}{14} )=11*(\frac{sinB}{11})\\\\\frac{11*sin100}{14} =sinB\\\\sinB=\frac{11*sin100}{14}[/tex]
Use the inverse:
[tex]B=sin^{-1}(\frac{11*sin100}{14})[/tex]
Insert the equation into a calculator and round to the nearest degree:
[tex]B=50.7\\\\B=51[/tex]
Angle B is 51°.

Gregor is planting pea plants in his backyard. Some of the plants are tall and the rest are short. Some of the plants are yellow and the rest are green. The numbers of different plant types are in the ratio\[\text{Tall green}:\text{Tall yellow}:\text{Short green}:\text{Short yellow} = 8:5:2:1.\]If there are 1080 green plants, then how many total plants are in Gregor's yard?
Answer:
1728.
Step-by-step explanation:
It is given that The numbers of different plant types are in the ratio
Tall green:Tall yellow:Short green:Short yellow = 8:5:2:1.
Let the numbers of Tall green, Tall yellow, Short green:, Short yellow are 8x, 5x, 2x, x respectively.
Number of green plants [tex]=8x+2x=10x[/tex]
It is given that there are 1080 green plants.
[tex]10x=1080[/tex]
[tex]x=108[/tex]
Number of total plants [tex]=8x+5x+2x+x=16x[/tex]
[tex]16x=16(108)=1728[/tex]
Therefore, total plants are in Gregor's yard is 1728.

How many twelfths equal two fourths
Answer: 6
Step-by-step explanation: Let n represent the number of twelfths in 5/4. Expressed symbolically, this is n/12 = 2/4. The LCD is 12. Multiply numerator and denominator of 2/4 by 3, obtaining: n/12 = 6/12 then n = 6. There are 6 twelves in 2/4.
There are 6 twelfths equal two fourths.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
We have to find twelfths equal two fourths
Let x represent the number of twelfths in 5/4.
So, the mathematical expression is
x/12 = 2/4.
Now, simplifying the fraction
x/ 12= 1/2
Now, multiply both side by 12
12 x/12 = 12/2
x= 6
Hence, there are 6 twelfths .

Find the 44th term in the following
arithmetic sequence :
2, 3, 4, 5, ...
Answer:
45
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 3 - 2 = 1, thus
[tex]a_{44}[/tex] = 2 + (43 × 1) = 2 + 43 = 45
Consider the triangle shown. Triangle R P Q is shown. Angle Q R P is 40 degrees. Angle R P Q is 105 degrees. Angle P Q R is 35 degrees. Which shows the sides in order from longest to shortest? Line segment P Q, line segment R Q, line segment R P Line segment R Q, Line segment P Q, line segment P Q Line segment R Q, line segment R P, line segment P Q Line segment R P, line segment P Q, line segment R Q
Answer:
RQ, PQ and RP.
Step-by-step explanation:
Note: Options are not correct.
From the given information, in triangle RPQ
[tex]\angle QRP=40^\circ[/tex]
[tex]\angle RPQ=105^\circ[/tex]
[tex]\angle PQR=35^\circ[/tex]
In a triangle, greatest angle has longest opposite side and smallest angle has shortest opposite side
Now,
[tex]\angle RPQ>\angle QRP>\angle PQR[/tex]
[tex]RQ>QP>PR[/tex]
[tex]RQ>PQ>RP[/tex]
Therefore, the order from longest to shortest is RQ, PQ and RP.
