K/3+4-5k=-2k what is the answer???
Answer:
Solve for k by simplifying both sides of the equation, then isolating the variable.
Exact Form: k = 3/2
Decimal Form: k = 1.5
Mixed Number Form: k = 1 1/2
Hope this helps!
Answer:
k = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{k}{3}[/tex] + 4 - 5k = - 2k
Multiply through by 3 to clear the fraction
k + 12 - 15k = - 6k
- 14k + 12 = - 6k ( add 14k to both sides )
12 = 8k ( divide both sides by 8 )
k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]

y=-x^3+ 4x^2 – 3 ; [0, 4]
Answer:
0 and 8/3
Step-by-step explanation:
y is continuous on [0,4]
It also also differentiable on (0,4)
Plugging in 0 and 4, we get -3 both times so y(0) = y(4).
Therefore there is at least one value c between 0 and 4 inclusive where y'(c) = 0
y' = -3x^2 + 8x
Set that to 0:
-3x^2 + 8x = 0
x(-3x+8) = 0
x = 0 or 8/3
And both values work.

Find the value of x. Round your answer to the nearest tenth
Answer:
[tex]x=42[/tex]
Step-by-step explanation:
Since we use the sides opposite and adjacent to the given angle, we will use the tangent ratio:
[tex]tangentX=\frac{opposite}{adjacent}[/tex]
Insert the given values:
[tex]tanX=\frac{9}{10}[/tex]
Since we need to find the angle, use the inverse:

C. $0.15 per message
D. $0.10 per message
Answer:
C.$0.15 I TOOK IT ON STUDY ISLAND
Step-by-step explanation:
First, you want to find an exact point on the graph. What I mean by this is you want to go somewhere on the graph where the line goes through an exact y and x value.
Second, you want to figure out where this x and y value are. Where the graph first goes through two points is at (20, 3).
Third, you want to figure out what the 20 and the 3 mean. 20 is the number of messages and 3 is the dollar amount.
Finally, to calculate the amount of money per message, you divide the dollar amount (3) by the number of messages (20). So, you have 3/20. After this, simplify 3/20 to get 0.15, or 15 cents per message.

Answer:
b = 18.56
c = 12.75
A = 40°
Step-by-step explanation:
Law of sines: a/sinA = b/sinB= c/sinC
12 / sin (180°-97°-43°) = b/sin97° = c/sin43°
12/sin40° = 12/0.64 = 18.75
b = 18.75 x sin97° = 18.75 x 0.99 = 18.56
c = 18.75 x sin 43° = 18.75 x 0.68 = 12.75
check: 12/sin40° = 12/0.64 = 18.75
b: 18.56 sin97°=0.99 18.56/0.99 = 18.747 ≈ 18.75
c: 12.75 sin43° = 0.68 12.75/0.68 = 18.75

Travis is deciding how to study math tonight he is choosing between studying ofG patterns P or equations E he also is deciding whether he should use a textbook T or videos V to study he’ll choose one topic in one method of learning which list shows all possible combinations of all Travis could study
Answer:
GT, GV, PT, PV, ET, and EV.
Step-by-step explanation:
Given that
The number of topics Travis has to chose from are 3 topics(G, P, E).
The number of ways Travis can study each topic are 2 ways(T, V).
Essentially, the number of combinations Travis is expected to be able to chose from is given as
The number of combinations = The number of topics * The number of ways
The number of combinations = 3 * 2
The number of combinations = 6
Therefore, the total possible combinations has to be
GT, GV, PT, PV, ET, and EV

Answer:
the answer is (1)
Step-by-step explanation:
k = am +3mx
i) factorize out m from the expressionk = m(a+3x)
ii) rearrange the equation using commutative propertym(a+3x) = k
iii) divide both sides of the equation by (a+3x)[tex] \frac{m(a+3x)}{(a + 3x)} = \frac{k }{(a + 3x)} [/tex]
[tex]m = \frac{k }{a + 3x} [/tex]
find an expression for the nth term (t_n) in each of the following
[tex]\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \frac{1}{n}}} [/tex]
Step-by-step explanation:A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,
[tex]\boxed{\boxed{\blue{\qquad\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}}}}[/tex]
When we flip the numbers , we can clearly see that the number are in Harmonic Progression.
That is when we flip the numbers they are found to be in Arithmetic Progression .
And nth term of an Harmonic Progression is :-
[tex]\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}} [/tex]
Hence here
Common difference = 1First term = 1 .Substituting the respective values,
[tex]\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}[/tex]
Hence the nth term of the given sequence is given by ¹/n .find the measurement of the missing angles
Answer:

A wire is first bent into the shape of a square. Each side of the square is 9cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 13cm, what is its width
Answer:
5 cm
Step-by-step explanation:
the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter
if the length of the rectangle is 13cm, its opposite side is also 13cm
add 13 + 13 to get 26
let 'n' = width of rectangle
perimeter = 26 + n + n
36 = 26 + 2n
2n = 10
n = 5
If the length of the rectangle is 13 cm then the width of the rectangle will be equal to 5 cm.
What is the perimeter?A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any two-dimensional geometric body. The circumference of several figures could be compared based on the measurements.
As per the information given in the question,
Length of the side of the square = 8 cm
Then, use the formula of the perimeter of the square = 4 × side
= 4 × 9 = 36 cm
The length of the rectangle = 13 cm
Use the formula of the perimeter of the rectangle,
P = 2(l + w)
36 = 2(13 + w)
36 -26 = 2w
w = 10/2
w = 5 cm

If a,b and c are the sides of a triangle where a = 12, b = 5 and c = 13 is this a right triangle ?
Answer:
yes
Step-by-step explanation:
To determine if the sides form a right triangle.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then triangle is right.
longest side is c = 13
13² = 169
a² + b² = 12² + 5² = 144 + 25 = 169
Since c² = a² + b² = 169
Then the sides form a right triangle
